51d9861e9e powerpc/mpc5200: Refactor FEC mdio read/write routines
Read & write functions now call a generic transfer function, so identical
code in both routines could be eliminated. The result is easier to maintain
and smaller in source and binary code. Also, fix some checkpatch warnings.

8713a7ccd8 rt2x00: fix regression introduced by "mac80211: free up 2 bytes in skb->cb"
The hw_key pointer is used (and obviously NULL) after skb->cb is
memset to 0. This patch grabs the iv_len before the memset call.

4233df6b74 ath9k/mac80211: disallow fragmentation in ath9k, report to userspace
As I've reported, ath9k currently fails utterly when fragmentation
is enabled. This makes ath9k "support" hardware fragmentation by
not supporting fragmentation at all to avoid the double-free issue.
The patch also changes mac80211 to report errors from the driver
operation to userspace.

That hack in ath9k should be removed once the rate control algorithm
it has is fixed, and we can at that time consider removing the hw
fragmentation support entirely since it's not used by any driver.

bc0da3fcec de2104x: wrong MAC address fix
The de2104x returns sometimes a wrong MAC address. The wrong one is
like the original one, but it comes with an one byte shift. I found
this bug on an older alpha ev5 cpu. More details are available in Gentoo
bugreport #240718.

It seems the hardware is sometimes a little bit too slow for an
immediate access. This patch solves the problem by introducing a small
udelay.

ef808d502c r8169: change default behavior for mildly identified 8168c chipsets
The addition of a new device has so far implied a specialization of

to be further refined as they have been by Realtek so far.

Broadly speaking the 8168c* share some common code which will
be factored in __rtl_hw_start_8168cp. The 8168b* share some
code too but it will be a bit different.

Any change of behavior should be confined to the currently
unidentified 8168 chipsets. They will not be applied the Tx
performance tweak and will emit a warning instead.

b836390159 r8169: shuffle some registers handling around (8168 operation only)
I can not argue strongly for (or against) a specific ordering
on a purely technical ground but the patch avoids to swallow
Realtek's changes in one big, hard-to-read gulp.

Let aside the way the RxConfig register is written (see
rtl_set_rx_tx_config_registers / RxConfig / rtl_set_rx_mode),
this change brings the registers write ordering closer with
Realtek's driver one (version 8.006.00) for the 8168 chipsets.

More 8168 specific code which touches the Configx registers will
be added in the section covered by Cfg9346_UnLock / Cfg9346_Lock.

This code should not be the cause of regression for 810x and
8110 users.

2. drivers/net/phy/fixed.c used to embed a struct mii_bus into its
   struct fixed_mdio_bus and then use container_of() to go from the
   former to the latter.  Since mii bus structures are no longer
   embedded, we need to do something like use the mii bus private

f231e0a5a2 cxgb3: More flexible support for PHY interrupts.
Do not require PHY interrupts to be connected to GPIs in ascending order.
Base interrupt availability both on PHYs supporting them and on GPIs being
hooked up.  Allows boards to specify interrupt GPIs though the PHYs don't
use them.

Remove spurious PHY interrupts due to clearing T3DBG interrupts before
setting their polarity.

d3eab82b55 gianfar: Create net device with carrier down
The device's carrier status is controlled via the functions
netif_carrier_on() and netif_carrier_off().  These set or clear a bit
indicating the carrier (aka lower level link) is down, and if the state
changed, they fire off a routing netlink event.

Add a call to netif_carrier_off() before register_netdev() so that the
newly created device will be set to carrier down.  Then when the carrier
comes up for the first time, a netlink event will be generated, as the
carrier changed from down to up.  Otherwise the initial carrier up will
appear to be changing the status from up to up, and so no event is
generated since that's not a change.

disable_irq_lockdep()/enable_irq_lockdep() used by __ei_poll(). Since
netconsole/netpoll always calls dev->poll_controller() with local irqs
disabled, disable_irq()/enable_irq() instead is safe and enough (like

ixgb would crash on PPC when an IOMMU was in use, if change_mtu was

It appears to be a pretty simple issue in the driver that wasn't discovered
because most systems don't run with an IOMMU.  The driver needs to only unmap
buffers that are mapped (duh).

But in recent kernels this implementation seems redundant and
can cause problems where AF_PACKET sees things twice. Since
NETIF_F_LLTX is marked as deprecated and shouldn't be used in
new driver, this patch removes NETIF_F_LLTX and adds a mmiowb
before sending packet. I have tested this driver on a Eee PC.

51e2a3846e PHY: Avoid unnecessary aneg restarts
The PHY's aneg is configured and restarted whenever the link is brought up,
e.g. when DHCP is started after the kernel has booted.  This can take the
link down for several seconds while auto-negotiation is redone.

If the advertised features haven't changed, then it shouldn't be necessary
to bring down the link and start auto-negotiation over again.

genphy_config_advert() is enhanced to return 0 when the advertised features
haven't been changed and >0 when they have been.

genphy_config_aneg() then uses this information to not call
genphy_restart_aneg() if there has been no change.

2f7fe87034 ath5k: implement multi-rate retry support, fix tx status reporting
Clean up the tx status reporting, fix retry counters (short retries are
virtual collisions, not actual retries). Implement multi-rate retry
support.
This also fixes strong throughput fluctuations with rc80211_pid

cf3e74c2e4 p54: report appropriate rate and band values for 802.11a
This patch adds the a few lines that went missing in
"p54: 802.11a 5GHz phy support"

Essentially: the rx-code wasn't updated and therefore reported the wrong band,
but more importantly the rate index was off as well, since 802.11a doesn't
allow the "four" 802.11b rates...

6f255425ac ath9k: enable ANI to help with noisy environments
This enables Adaptive Noise Immunity (ANI) on ath9k.
ANI is as algorithm designed to minimize the detrimental
effects of time-varying interferences. This should
help with throughput in noisy environments. To use
ANI we re-enable the MIB interrupt. Since ANI works
on a timer and updates the noise floor we take
advantage of this and also report a non-static noise
floor now to mac80211.

95b866d5af e1000e: Fix incorrect debug warning
Doing 'WARN_ON(preempt_count())' was horribly horribly wrong, and would
cause tons of warnings at bootup if PREEMPT was enabled because the
initcalls currently run with the kernel lock, which increments the
preempt count.

At the same time, the warning was also insufficient, since it didn't
check that interrupts were enabled.

The proper debug function to use for something that can sleep and wants
a warning if it's called in the wrong context is 'might_sleep()'.

a8f88ff5a5 e1000e: do not ever sleep in interrupt context
e1000e was apparently calling two functions that attempted to reserve
the SWFLAG bit for exclusive (to hardware and firmware) access to
the PHY and NVM (aka eeprom).  These accesses could possibly call
msleep to wait for the resource which is not allowed from interrupt
context.
