bd43da8ff1 [MIPS] tc35815: Load MAC address via platform_device
TX49XX SoCs include PCI NIC (TC35815 compatible) connected via its
internal PCI bus, but the NIC's PROM interface is not connected to
SEEPROM.  So we must provide its ethernet address by another way.

44e4925e46 e100: Fix Tyan motherboard e100 not receiving IPMI commands
The 82550 & 51 parts have an extended configuration block that
includes a bit "GMRC", required to enable the expected TCO behavior,
in config byte offset 22d.  The config block sent by the failing driver
does include the extension area, but this bit is not initialised,
and the downlaod only specifies 0x16 bytes to be sent to the NIC
(thaht's bytes 00..21d). By initializing the GMRC bit, and extending
the download size for D102+ MACs, the problem is resolved.

7a62755821 spidernet: improve interrupt handling
We intend this patch to improve spidernet interrupt handling to be
more strict.  We had following problem and this patch solves it.

 -when CONFIG_DEBUG_SHIRQ=y, request_irq() calls handler().
 -when spider_net_open() is called, it calls request_irq() which calls
  spider_net_interrupt().
 -if some specific interrupt bit is set at this timing, it calls
  netif_rx_schedule() and spider_net_poll() is scheduled.
 -spider_net_open() calls netif_poll_enable() which clears the bit
  __LINK_STATE_RX_SCHED.
 -when spider_net_poll() is called, it calls netif_rx_complete() which
  causes BUG_ON() because __LINK_STATE_RX_SCHED is not set.

b8a1fcee26 3cSOHO100-TX needs EXTRA_PREAMBLE
The 3cSOHO100-TX needs a mdio_sync() before mdio_read() to read the MII
transceiver registers properly.  Adding EXTRA_PREAMBLE to drv_flags of the
3cSOHO100-TX will force this.

This problem exists already for years (I checked back to 2.6.8).
Setting duplex for the 3cSOHO100-TX was more or less a random process.
Till 2.6.15 it was more likely that the diver ends up in half
duplex mode, after the code change in 2.6.16 it was more likely
to end up in full duplex mode. I wonder why nobody noticed this earier.

Hopefully addresses

de3d353072 RDMA/cxgb3: Streaming -> RDMA mode transition fixes
Due to a HW issue, our current scheme to transition the connection from
streaming to rdma mode is broken on the passive side.  The firmware
and driver now support a new transition scheme for the passive side:

 - driver posts rdma_init_wr (now including the initial receive seqno)
 - driver posts last streaming message via TX_DATA message (MPA start
   response)
 - uP atomically sends the last streaming message and transitions the
   tcb to rdma mode.
 - driver waits for wr_ack indicating the last streaming message was ACKed.

NOTE: This change also bumps the required firmware version to 4.3.

864022344c r8169: confusion between hardware and IP header alignment
The rx copybreak part is straightforward.

The align field in struct rtl_cfg_info is related to the alignment
requirements of the DMA operation. Its value is set at 2 to limit the
scale of possible regression but my old v1.21 8169 datasheet claims a
8 bytes requirements (which never appeared in the driver, of course)
and the 8101/8168 go with a plain 8 bytes alignment.

- more magic in rtl_hw_start_8169

- it is not possible to factor out the setting of the the irq event mask
  with the 8168 and the 8101 any more. Pushed it into the hw_start handler.

- rtl_set_rx_tx_config_registers() and write to the ChipCmd register are

  are handled the same way

- work around for AMD platform.

07ce406467 r8169: add hooks for per-device hw_start handler
Rationale: rtl8169_hw_start will not help maintaining an unified
driver for different chipsets but people at Realtek are probably
too polite to say it distinctly.

Let's add the hook and keep hw_start handler unchanged.

As can be seen from the content of rtl8169_pci_tbl, the RTL_CFG_1
entry in rtl_cfg_info was unused. I recycled it for the 0x8168.

even though they are not actually any newer than the in-tree version.

aaf83d4fc4 [PATCH] zd1211rw: Make CCK gain patching conditional on RF type
The vendor driver code suggests that CR47 patching happens on every channel
change for every RF (depending on bit 8 in POD).

Due to a bug in their driver (upper bits of RF_Mode get zeroed out, then
are examined for 1s when setting some other flags), this isn't actually
what happens, and their generic CCK patching routine never takes effect.

Some of their RF configurations do include explicit (duplicated) code
for CR47 patching though. This patch makes zd1211rw match that
behaviour.

This patch adds support for another radio appearing in new devices: the
Ubec UW2453. It's more complicated than the other RF's we support, but
Ubec publish full tech specs so we're able to understand the vendor code
relatively well.

Now that we support UW2453, we also support Atheros' new USB chip: the
AR5007UG. From the little info we have, this appears to be just a
rebranded ZD1211B.

This RF code doesn't work very well -- lots more TX/RX errors than the
other RFs. However, the vendor driver doesn't do any better, so this is
all we can do for now.

0da2f0f164 potential compiler error, irqfunc caller sites update
In 7d12e780e0 David Howells performed
this evolution:
 "IRQ: Maintain regs pointer globally rather than passing to IRQ handlers"

He correctly updated many of the function definitions that were using this
extra regs pointer parameter but forgot to update some caller sites of
those functions.  The reason the modifications was not properly done on all
drivers is that some drivers were rarely compiled because they are for
AMIGA, or that some code sites were inside #ifdefs where the option is not
set or inside #if 0.

Here is the semantic patch that found the occurences
and fixed the problem.

Don't use PNP detection by default yet.  We have some PNP and BIOS issues
to work out first.

Sample problem on a Toshiba Portege 4000: the SMCf010 device is handed off
disabled.  We assign I/O ports originally assigned to the SMCf010 to a
PCMCIA device instead.  We enable the SMCf010, configuring it to use
disjoint ports, but _SRS doesn't work correctly, so the device doesn't
work.

59faba1b31 Fix Kconfig dependency problems wrt boolean menuconfigs
If one has a dependency chain (tristate)FOO depends on (bool)BAR depends on
(tristate)BAZ, build problems will result.  If BAZ=m, then BAR can be set
y, which allows FOO=y.  It's possible to have FOO=y && BAZ=m, which
wouldn't be allowed if FOO depended directly on BAZ.  In effect, the bool
promotes the tristate from m to y.

This ends up causing a problem with several menuconfigs that look like:

menuconfig BAR
	bool
	depends on BAZ [tristate]
if BAR
config FOO
	tristate
endif

The solution used here is to add the dependencies of BAR to the if
statement, so that items in the if block will gain a direct
non-bool-promoted dependency on BAZ.  This is how it would work if a menu
was used instead of an if block.

7c31d2f59c smsc-ircc2: skip preconfiguration for PNP devices
If we rely on the device resources from PNPBIOS, we also have to rely on
the BIOS to configure any bridges on the way to the device.

Using the PNPBIOS resources but changing the configuration of a bridge
behind the back of the firmware is likely to make things inconsistent.

This patch addresses part of the 2.6.22 regression:
    "no irda0 interface (2.6.21 was OK), smsc does not find chip"
It fixes smsc-ircc2 PNP device detection on HP nx5000 laptops.
Other laptops, including HP nc6000, HP nc8000, HP nw8000, and Toshiba
Portege 4000, still need PNP quirks to make this work.

With "smsc-ircc2.nopnp", we do the legacy device probe, including manual
bridge preconfiguration, as before.

NVREG_PFF_ALWAYS|NVREG_PFF_MYADDR (i.e., receive unicast packets to my

It doesn't look like spidernet hardware can really checksum all protocols,
the code looks like it does IPV4 only.  If so, it should use NETIF_F_IP_CSUM
instead of NETIF_F_HW_CSUM.

128c6e2e51 spidernet: turn off descriptor chain end interrupt.
At some point, the transmit descriptor chain end interrupt (TXDCEINT)
was turned on. This is a mistake; and it damages small packet
transmit performance, as it results in a huge storm of interrupts.

2bf27a0d49 spidernet: Don't terminate the RX ring
The terminated RX ring will cause trouble during the RX ram full
conditions, leading to a hung driver, as the hardware can't find
the next descr.  There is no real reason to terminate the RX ring;
it doesn't make the operation any smooother, and it does
require an extra sync. So don't do it.

4c4bd5a97a spidernet: Cure RX ram full bug
This patch fixes a rare deadlock that can occur when the kernel
is not able to empty out the RX ring quickly enough. Below follows
a detailed description of the bug and the fix.

As long as the OS can empty out the RX buffers at a rate faster than
the hardware can fill them, there is no problem. If, for some reason,
the OS fails to empty the RX ring fast enough, the hardware GDACTDPA
pointer will catch up to the head, notice the not-empty condition,
ad stop. However, RX packets may still continue arriving on the wire.
The spidernet chip can save some limited number of these in local RAM.
When this local ram fills up, the spider chip will issue an interrupt
indicating this (GHIINT0STS will show ERRINT, and the GRMFLLINT bit
will be set in GHIINT1STS).  When te RX ram full condition occurs,
a certain bug/feature is triggered that has to be specially handled.
This section describes the special handling for this condition.

When the OS finally has a chance to run, it will empty out the RX ring.
In particular, it will clear the descriptor on which the hardware had
stopped. However, once the hardware has decided that a certain
descriptor is invalid, it will not restart at that descriptor; instead
it will restart at the next descr. This potentially will lead to a
deadlock condition, as the tail pointer will be pointing at this descr,
which, from the OS point of view, is empty; the OS will be waiting for
this descr to be filled. However, the hardware has skipped this descr,
and is filling the next descrs. Since the OS doesn't see this, there
is a potential deadlock, with the OS waiting for one descr to fill,
while the hardware is waiting for a differen set of descrs to become
empty.

A call to show_rx_chain() at this point indicates the nature of the
problem. A typical print when the network is hung shows the following:

net eth1: Spider RX RAM full, incoming packets might be discarded!
net eth1: Total number of descrs=256
net eth1: Chain tail located at descr=255
net eth1: Chain head is at 255
net eth1: HW curr desc (GDACTDPA) is at 0
net eth1: Have 1 descrs with stat=xa0800000
net eth1: HW next desc (GDACNEXTDA) is at 1
net eth1: Have 127 descrs with stat=x40800101
net eth1: Have 1 descrs with stat=x40800001
net eth1: Have 126 descrs with stat=x40800101
net eth1: Last 1 descrs with stat=xa0800000

Both the tail and head pointers are pointing at descr 255, which is
marked xa... which is "empty". Thus, from the OS point of view, there
is nothing to be done. In particular, there is the implicit assumption
that everything in front of the "empty" descr must surely also be empty,
as explained in the last section. The OS is waiting for descr 255 to
become non-empty, which, in this case, will never happen.

The HW pointer is at descr 0. This descr is marked 0x4.. or "full".
Since its already full, the hardware can do nothing more, and thus has
halted processing. Notice that descrs 0 through 254 are all marked
"full", while descr 254 and 255 are empty. (The "Last 1 descrs" is
descr 254, since tail was at 255.) Thus, the system is deadlocked,
and there can be no forward progress; the OS thinks there's nothing
to do, and the hardware has nowhere to put incoming data.

This bug/feature is worked around with the spider_net_resync_head_ptr()
routine. When the driver receives RX interrupts, but an examination
of the RX chain seems to show it is empty, then it is probable that
the hardware has skipped a descr or two (sometimes dozens under heavy
network conditions). The spider_net_resync_head_ptr() subroutine will
search the ring for the next full descr, and the driver will resume
operations there.  Since this will leave "holes" in the ring, there
is also a spider_net_resync_tail_ptr() that will skip over such holes.

0e6e741621 IB/mlx4: Handle new FW requirement for send request prefetching
New ConnectX firmware introduces FW command interface revision 2,
which requires that for each QP, a chunk of send queue entries (the
"headroom") is kept marked as invalid, so that the HCA doesn't get
confused if it prefetches entries that haven't been posted yet.  Add
code to the driver to do this, and also update the user ABI so that
userspace can request that the prefetcher be turned off for userspace
QPs (we just leave the prefetcher on for all kernel QPs).

Unfortunately, marking send queue entries this way is confuses older
firmware, so we change the driver to allow only FW command interface
revisions 2.  This means that users will have to update their firmware
to work with the new driver, but the firmware is changing quickly and
the old firmware has lots of other bugs anyway, so this shouldn't be too
big a deal.

Based on a patch from Jack Morgenstein <jackm@dev.mellanox.co.il>.

82fde74b94 [PATCH] libertas: convert libertas_mpp into anycast_mask
With firmware 5.220.11.p5, this allows to specify the anycast addresses the
device will listen to.

The anycast address range is C0:27:C0:27:C0:XX where XX goes from 00 to 1F (or
0 to 31 in dec). The value to write on anycast_mask will specify which
addresses the device listens to. Bits in a 32 bit int are numbered from 0
(least significative bit) to 31. A specific address ending in YY will be
listened to if bit YY in the value is set to one.

Examples:

0x00000000 : do not listen to any anycast address
0xFFFFFFFF : listen to every anycast address from :00 to :1F
0x00000013 : listen to anycast addresses :00, :01 and :04

90a42210f2 [PATCH] libertas: Make WPA work through supplicant handshake
Fix WPA so it works up through the supplicant 4-Way handshake process.
Doesn't successfully pass traffic yet; may be problems installing
the GTK to the firmware.

- RSN needs to be enabled before the association command is sent
- Use keys from the association request not the adapter structure
- cmd_act_mac_strict_protection_enable != IW_AUTH_DROP_UNENCRYPTED
- Fix network filtering logic in is_network_compatible() WPA helpers

Previously if a fixed channel was specified along with an SSID,
the channel request would be ignored during the association

that the driver doesn't pick a BSS on a different channel than
requested.

e76850d620 [PATCH] libertas: make association paths consistent
The BSS to associate with (in either Infrastructure or IBSS join
operations) is now stored in _one_ place in the association request (the
bss member), not two places as before (pattemptedbss and
curbssparams->bssdescriptor).

Association requests are passed to the necessary association functions
to (a) give them access to the bss member and (b) ensure that
association/join/start setup uses settings from the request, not the
current adapter settings (which may not be valid for the requested
settings).

Because the 'bss' member of the association request is used now, the
command return functions from associate and adhoc join/start need access
to the in-progress association request to update curbssparams when
everything is done.  The association worker moves the request from
pending to in-progress for the duration of the association attempt.

Actually, this patch removev wlan_dev_t totally and puts the used variables

"priv->wlan_dev.card" and "priv->dev" instead of "priv->wlan_dev.netdev"

Changed two occurences of "((wlan_private *) dev->priv)->wlan_dev.netdev"
into "dev", because I didn't see the point in doing pointer-ping-pong.

The variables "ioport", "upld_rcv" and "upld_type" where unused. They have

064827edf6 [PATCH] libertas: scan two channels per scan command
Scan two channels per each command on set_scan(), then bail out and let
get_scan() continue the scanning work up to the last channel.

This gives time to the firmware so it can go back to the association
channel and keep the connection alive.

Replace invisible character with a space.

The diff looks like this on my terminal:
-        <A0>Choose this option if you're using a host-to-host cable
-        <A0>with one of these chips.
+         Choose this option if you're using a host-to-host cable

895ee682db phylib: add RGMII-ID mode to the Marvell m88e1111 PHY to fix broken ucc_geth
Support for configuring RGMII-ID (RGMII with internal delay) mode on the
88e1111 and 88e1145.  Ucc_geth on MPC8360EMDS(the main user of ucc_geth)
is broken after changed to use phylib.  It is fixed by adding this
internal delay.

Also renamed 88e1111s -> 88e1111 (no references to an 88e1111s part were
found), and fixed some whitespace.

0d04761d17 NetXen: Fix compile failure seen on PPC architecture
NetXen: Add NETXEN prefixes to macros to clean them up.
This is a cleanup patch which adds NETXEN prefix to some stand
alone macro names.
These posed compile errors when NetXen driver was backported to 2.6.9
on PPC architecture as macros like USER_START are defined in file
arch/ppc64/mm/hash_utils.c

3e2facef86 NetXen: Fix ping issue after reboot on Blades with 3.4.19 firmware
NetXen: Fix initialization and subsequent ping issue on 3.4.19 firmware
This patch fixes the ping problem seen X/PBlades after the adapter's
firmware was moved to 3.4.19. After configured interface up, ping
failed.
NetXen adapter couldn't accept ARP broadcast packet. Manual addition of
MAC address in the ARP table, made ping work.
NetXen adapter should finish initilization after system boot. But looks
NetXen adapter didn't initilization correctly after system boot up.
So have to re-load the firmware again in probe routine.
Also re-initilization netxen_config_0 and netxen_config_1 registers.
