Erik Hugne's errata proposal (Errata ID: 3480) to RFC4291 has been
verified: http://www.rfc-editor.org/errata_search.php?eid=3480

We have to check for pkt_type and loopback flag because either the
packets are allowed to travel over the loopback interface (in which case
pkt_type is PACKET_HOST and IFF_LOOPBACK flag is set) or they travel
over a non-loopback interface back to us (in which case PACKET_TYPE is
PACKET_LOOPBACK and IFF_LOOPBACK flag is not set).

The sky2 driver sets the Rx Upper Threshold for Pause Packet generation to a
wrong value which leads to only 2kB of RAM remaining space. This can lead to
Rx overflow errors even with activated flow-control.

The sky2 driver doesn't count the Receive Overflows because the MAC
interrupt for this event is not set in the MAC's interrupt mask.
The MAC's interrupt mask is set only for Transmit FIFO Underruns.

Fix: The correct setting should be (GM_IS_TX_FF_UR | GM_IS_RX_FF_OR)
Otherwise the Receive Overflow event will not generate any interrupt.
The  Receive Overflow interrupt is handled correctly

John W. Linville says:

====================
Please excuse this larger-than-I-would-like pull request intended
for the 3.9 stream.  There are a number of late-breaking fixes,
including a revert...

Regarding the mac80211 bits, Johannes says:

"I have two tracing fixes (one from Vladimir), two fixes for P2P device
crashes, a fix for a BSS memory leak/lost update problem and a fix from
Ben for a scanning issue in mac80211. It's a little on the large side
because one of the P2P device problems required a bit much locking work,
but I've run through all the different scenarios (wext/nl80211,
p2p-device/station interface, ifdown/rfkill) to verify locking with
lockdep."

As for the iwlwifi bits, Johannes says:

"I have three little fixes to the driver from Emmanuel. One addresses a
small bug Ben Hutchings found during the stable review process and two
address some warnings in the driver when RF-Kill is asserted."

Along with those...

Avinash Patil fixes an mwifiex bug cause by failing to process a sleep
command due to bad SKB manipulation when going into power saving mode.

Colin Ian King avoids a null pointer dereference in iwl4965.

Dan Williams officially announces that he has dropped maintainership
of the libertas driver.

Iestyn C. Elfick adds a work-around to avoid b43 DMA transmision
sequence error that would lead to a device reset.

Luis R. Rodriguez avoids an ath9k warning by not queueing a work item
while going to suspend mode.

Rafał Miłecki provides a pair of b43 N-PHY fixes related to RSSI
calibration.

Finally, I revert "brcmsmac: support 4313iPA" because it has been
reported in many places to cause problems with the already supported
4313ePA devices.

Some network drivers use a non default hard_header_len

Transmitted skb should take into account dev->hard_header_len, or risk

====================
here's a patch series for net for the v3.9 release cycle. Fengguang Wu found
two problems with the sja1000 drivers:

A macro in the SH architecture collides with one in the sja1000 driver. I
created a minimal patch suited for stable, only changing this particular
define. (Once net is merged back to net-next, I'll post a patch to uniformly
use a SJA1000_ prefix for the sja100 private defines.) If you prefer, I can
squash both patches together.

Fengguang further noticed that the peak pcmcia driver will not compile on archs
without ioport support. I created a patch to limit the driver to archs which
select HAS_IOPORT in Kconfig.

Commit 184b8904 ("tg3: Use VPD fw version

overflow.

Limit the hardware's reported firmware string length (max 255 bytes) to
stay inside the driver's firmware string length (32 bytes). On overflow,
truncate the formatted firmware string instead of potentially overwriting
portions of the tg3 struct.

When calculating "offset" for final RSSI calibration we're using numbers
bigger than s8 can hold. We have for example:
offset[j] = 232 - poll_results[j];
formula. If poll_results[j] is small enough (it usually is) we treat
number's bit as a sign bit. For example 232 - 1 becomes:
0xE8 - 0x1 = 0xE7, which is not 231 but -25.

Intermittently, b43 will report "Out of order TX status report on DMA ring".
When this happens, the driver must be reset before communication can resume.
The cause of the problem is believed to be an error in the closed-source
firmware; however, all versions of the firmware are affected.

This change uses the observation that the expected status is always 2 less
than the observed value, and supplies a fake status report to skip one
header/data pair.

Not all devices suffer from this problem, but it can occur several times
per second under heavy load. As each occurence kills the unmodified driver,
this patch makes if possible for the affected devices to function. The patch
logs only the first instance of the reset operation to prevent spamming
the logs.

The thing is, wrt fairness lglocks are more similar to rwsems than to rwlocks;
it is possible to have thread B spin on attempt to take lock shared while thread
A is already holding it shared, if B is on lower-numbered CPU than A and there's
a thread C spinning on attempt to take the same lock exclusive.

As the result, we need consistent ordering between vfsmount_lock (lglock) and
rename_lock (seq_lock), even though everything that takes both is going to take
