22c96c28b4 rt2x00: Add chipset version to chipset debugfs entry
The chipset debugfs entry already indicates it is about the chipset,
it only makes sense to also display the chipset version in there.

013978b688 b43: Changes to enable BCM4311 rev 02 with wireless core revision 13
The BCM94311MCG rev 02 chip has an 802.11 core with revision 13 and
has not been supported until now. The changes include the following:

(1) Add the 802.11 rev 13 device to the ssb_device_id table to load b43.
(2) Add PHY revision 9 to the supported list.
(3) Change the 2-bit routing code for address extensions to 0b10 rather
    than the 0b01 used for the 32-bit case.
(4) Remove some magic numbers in the DMA setup.

The DMA implementation for this chip supports full 64-bit addressing with
one exception. Whenever the Descriptor Ring Buffer is in high memory, a
fatal DMA error occurs. This problem was not present in 2.6.24-rc2 due
to code to "Bias the placement of kernel pages at lower PFNs". When
commit 44048d70 reverted that code, the DMA error appeared. As a "fix",
use the GFP_DMA flag when allocating the buffer for 64-bit DMA. At present,
this problem is thought to arise from a hardware error.

This patch has been tested on my system and by Cédric Caumont
<icare40@hotmail.com>.

3a18864917 libertas: rework event subscription
This patch moves re-works the implementation of event subscription
via debugfs. For this:

* it tells cmd.c and cmdresp.c about CMD_802_11_SUBSCRIBE_EVENT
* removes lots of low-level cmd stuff from debugfs.c
* create unified functions to read/write snr, rssi, bcnmiss and
  failcount
* introduces #define's for subscription event bitmask values
* add a function to search for a specific element in an IE
  (a.k.a. TLV)
* add a function to find out the size of the TLV. This is needed
  because lbs_prepare_and_send_command() has an argument for a
  data buffer, but not for it's lengths and TLVs can be, by
  definition, vary in size.
* fix a bug where it was not possible to disable an event

be13f1897f libertas: reset devices upon disconnect rather than module unloading
1) Do not reset libertas devices upon module unload.  We're unloading
the module, we're not killing off devices.
2) Instead, reset libertas devices inside if_usb_disconnect, as we're
killing off interfaces and so on.
3) Resetting via disconnect callback means we no longer need to keep
track of probed libertas devices; kill off that list (and its wonderful
lack of locking..), as well.

Don't enable RX/TX of packets until we have a link, since there's a chance
we'll just get RX frame errors, etc.

The case where we don't have a PHY we can't do much about: Just enable
it and deal with errors as they come in.

906674abab pasemi_mac: Improve RX interrupt mitigation
pasemi_mac: Improve RX interrupt mitigation

Currently the receive side interrupts will go off on the reception of
a packet, NAPI will poll the ring and keep polling as long as there's
a decent amount of packets to receive.

This is less than optimal, especially for LRO where it's better if we
have a more substantial amount of packets to process at once, to get
the real LRO benefits.

So, set the count threshold to a higher value and use the timeout feature
that will give us an interrupt even if not enough packets have come in
to set off the count threshold.

FIXME: It'd be real nice to have ethtool support for users to tune this
at runtime.

61cec3bddc pasemi_mac: Fix TX cleaning
pasemi_mac: Fix TX cleaning

This is a bit awkward. We don't have a timer-delayed interrupt on TX
complete, but we have a count threshold. So set that reasonably high
(32 packets), and schedule the NAPI poll when it goes off. Also bump a
regular timer that will take care of rotting packets for the last 1..31
ones in case we don't trigger a TX interrupt (and there's no RX activity
that would otherwise trigger the poll).

The longer-term fix is to separate TX from RX NAPI and do two separate
poll loops.

When using larger MTU's sky2 driver changes from allocating one
data area, to using multiple pages. The threshold for this was based on
a heuristic where the cost of a single allocation is bigger than one
page.  Since the allocator has changed, this heuristic is now incorrect;
instead just make the threshold be when the total size of the allocation
is greater than one page.

7734f6e6bc Fix e100 on systems that have cache incoherent DMA
On the systems that have cache incoherent DMA, including ARM, there
is a race condition between software allocating a new receive buffer
and hardware writing into a buffer.  The two race on touching the last
Receive Frame Descriptor (RFD).  It has its el-bit set and its next
link equal to 0.  When hardware encounters this buffer it attempts to
write data to it and then update Status Word bits and Actual Count in
the RFD.  At the same time software may try to clear the el-bit and
set the link address to a new buffer.

Since the entire RFD is once cache-line, the two write operations can
collide.  This can lead to the receive unit stalling or interpreting
random memory as its receive area.

The fix is to set the el-bit on and the size to 0 on the next to last
buffer in the chain.  When the hardware encounters this buffer it stops
and does not write to it at all.  The hardware issues an RNR interrupt
with the receive unit in the No Resources state.  Software can write
to the tail of the list because it knows hardware will stop on the
previous descriptor that was marked as the end of list.

Once it has a new next to last buffer prepared, it can clear the el-bit
and set the size on the previous one.  The race on this buffer is safe
since the link already points to a valid next buffer and the software
can handle the race setting the size (assuming aligned 16 bit writes
are atomic with respect to the DMA read). If the hardware sees the
el-bit cleared without the size set, it will move on to the next buffer
and skip this one.  If it sees the size set but the el-bit still set,
it will complete that buffer and then RNR interrupt and wait.

of heuristic but there no reason to make ioctl more ugly than needed.

3957d63da0 ixgbe: Fix copper PHY initialization code
While cleaning up the internal API focussing on Fiber and CX4 code
we found that I had broken the copper PHY initialization code. This
patch restores the PHY-specific code. This is mostly uninteresting
since no copper PHY boards are yet available. The changes have been
tested against Fiber only as I do not even have copper PHY versions
of 82598 macs.

This change actually cleans up the API code a bit more and we
lose some initialization code. A few PHY link detection helper
lines of code have been snuck into this patch, as well as a
read flush where it was suspected that this might cause issues.

040babf9d8 e1000/e1000e: Move PCI-Express device IDs over to e1000e
e1000e will from now on support the PCI-Express adapters that
previously were supported by e1000. This support means better
performance and easier debugging from now on for both the old
PCI-X/PCI hardware and PCI-Express adapters.

This patch also moves 3 recently merged device IDs over to e1000e
that are identical to quad-port versions of already existing
dual port versions. With this last bit every former e1000 pci-e
device should work now with e1000e.

Here is a brief list of which gigabit driver to use with which
adapter:

  e1000:
	82540 -> 82547

  e1000e:
	82571 -> 82573
	ich8, ich9       (82562 or 82566)
	es2lan           (80003eslan)

  igb: (not yet merged, only available from e1000.sf.net)
	82575

1eae4eb2a1 e1000e: Disable L1 ASPM power savings for 82573 mobile variants
L1 ASPM link (pci-e link power savings) has significant benefits
(~1W savings when link is active) but unfortunately does not work
correctly on any of the chipsets that have 82573 on mobile platforms
which causes various nuisances:
 - eeprom reads return garbage information leading to bad eeprom
   checksums
 - long ping times (up to 2 seconds)
 - complete system hangs (freeze/lockup)

A lot of T60 owners have been plagued by this, but other mobile
solutions also suffer from these symptoms.

Disabling L1 ASPM before we activate the PCI-E link fixes all of
these issues at the cost of some power consumption.

Remove a workaround RDTR adjustment that is no longer needed with
this new one.

ef878b8899 sk98lin: kill bogus check and convert to use ARRAY_SIZE()
This converts uses of ARRAY_SIZE(), and while at it also kills
unreachable code as far as I can say. I can't tell what was the author
trying to do with the following check. First we have:

PNMI_STATIC const SK_PNMI_STATADDR
		StatAddr[SK_PNMI_MAX_IDX][SK_PNMI_MAC_TYPES];

and then a check goes like this:

if (SK_PNMI_MAX_IDX !=
   (sizeof(StatAddr) / (sizeof(SK_PNMI_STATADDR) * SK_PNMI_MAC_TYPES)))

with the second line being just ARRAY_SIZE(StatAddr), which will always
return SK_PNMI_MAX_IDX, rendering the check useless.
