9e555930bd forcedeth boot delay fix
Fix a long boot delay in the forcedeth driver.  During initialization, the
timeout for the handshake between mgmt unit and driver can be very long.
The patch reduces the timeout by eliminating a extra loop around the
timeout logic.

61dbcecef5 ibm_newemac: Fix possible lockup on close
It's a bad idea to call flush_scheduled_work from within a
netdev->stop because the linkwatch will occasionally take the
rtnl lock from a workqueue context, and thus that can deadlock.

This reworks things a bit in that area to avoid the problem.

279e1dab94 Revert "skge: fix ram buffer size calculation"
This reverts commit 7fb7ac2411.

Heikki Orsila reports that it causes a regression:

  "Doing

	nc host port < /dev/zero

   on a sending machine (not skge) to an skge machine that is receiving:

	nc -l -p port >/dev/null

   with ~60 MiB/s speed, causes the interface go malfunct. A slow
   transfer doesn't cause a problem."

See

	http://bugzilla.kernel.org/show_bug.cgi?id=9321

for some more information.

There is a workaround (also reported by Heikki):

  "After some fiddling, I noticed that not changing the register write
   order on patch:

   +       skge_write32(hw, RB_ADDR(q, RB_END), end);
           skge_write32(hw, RB_ADDR(q, RB_WP), start);
           skge_write32(hw, RB_ADDR(q, RB_RP), start);
   -       skge_write32(hw, RB_ADDR(q, RB_END), end);

   fixes the visible effect..  Possibly not the root cause of the
   problem, but changing the order back fixes networking here."

but that has yet to be ack'ed or tested more widely, so the whole
problem-causing commit gets reverted until this is resolved properly.

bafef0ae9d cris build fixes: update eth_v10.c ethernet driver
New (updated) version of ethernet driver for cris v10.

- First steps to simplify and make the MII code more similar
  between the etrax100 and etraxfs ports.

- Start the transmit queue before enabling tx interrupts
  to avoid race with the first frame.

- Flip the comparition statement to stick to physical addresses
  to avoid phys_to_virt mapping a potential null pointer.
  This was not an error but the change simplifies debugging
  of address-space mappings.

- Made myPrevRxDesc local to e100_rx since it was only used there.
  Fixed out of memory handling in e100_rx.  If dev_alloc_skb() fails
  persistently the system is hosed anyway but at least it won't
  loop in an interrupt handler.

- Correct some code formatting issues.

- Add defines SET_ETH_ENABLE_LEDS, SET_ETH_DISABLE_LEDS
  and SET_ETH_AUTONEG used in new cris v10 ethernet driver.

755a957d40 rt2x00: Fix chipset revision validation
The validation of the chipset revision was broken
since for rt2500usb and rt73usb different registers
should be read. When rt2500usb was loaded for a rt73
device it would false think the chipset was correct
because the wrong register was read and validated.

This has been fixed by expanding the check to also
see if the first 4 bits of the revision is not-0
(When reading the wrong register offset the returned
value is usually 0 which can be interpreted as invalid)

During normal operation, the MAC depends on the PHY clock being
available.  When the PHY is powered down, the clock the MAC depends on
is disabled.  The fix is to switch the MAC clock to an alternate source
before powering down the PHY, and to restore the MAC clock to the PHY
source upon device resume.

c88864df27 [TG3]: Fix 5761 PXEboot crash
When 5761 devices boot the machine using PXEboot, PXE leaves the device
active when it terminates.  The tg3 driver has code to detect this
condition and resets the device during initialization.  On 5761 devices,
device resets involve sending a driver state update message to the APE
on the 5761.  However, during this initialization stage, communications
to the APE registers have not yet been set up.  The driver then
dereferences a NULL pointer and crashes the machine.  The fix is to move
the APE register access setup earlier in the initialization code to
cover this condition.

62768e28d6 [SUNGEM]: Fix suspend regression due to NAPI changes.
Commit bea3348e (the NAPI changes) made sungem unconditionally enable
NAPI when resuming and unconditionally disable when suspending, this,
however, makes napi_disable() hang when suspending when the interface
was taken down before suspend because taking the interface down also
disables NAPI. This patch makes touching the napi struct in
suspend/resume code paths depend on having the interface up, thereby
fixing the hang on suspend.

The patch also moves the napi_disable() in gem_close() under the lock so
that the NAPI state is always modified atomically together with the
"opened" variable.

f51359a8fb iwlwifi: select proper rate control algorithm
Prior to this patch, iwlwifi would always use the first
registered rate control algorithm which, depending on system
setup, could be anything. After the mac80211 patch to make
the simple algorithm built-in, it would always be simple.

This has always been a bug in iwlwifi.

This fixes it by requesting that mac80211 selects the right
rate control algorithm.

a6baf3af89 r8169: prevent bit sign expansion error in mdio_write
Oops.

The current code does not like being given an u16 with the highest
bit set as an argument to mdio_write. Let's enforce a correct range of
values for both the register address and value (resp. 5 and 16 bits).

The callers are currently left as-is.
