Pull networking fixes from David Miller:

1) TCP SACK processing can calculate an incorrect reordering value in
   some cases, fix from Neal Cardwell.

2) tcp_mark_head_lost() can split SKBs in situations where it should
   not, violating send queue invariants expected by other pieces of
   code and thus resulting (eventually) in corrupted retransmit state
   counters.  Also from Neal Cardwell.

3) qla3xxx erroneously calls spin_lock_irqrestore() with constant
   hw_flags of zero.  Fix from Santosh Nayak.

4) Fix NULL deref in rt2x00, from Gabor Juhos.

5) pch_gbe passes address of wrong typed object to pch_gbe_validate_option
   thus corrupting part of the value.  From Dan Carpenter.

6) We must check the return value of nlmsg_parse() before trying to use
   the results.  From Eric Dumazet.

7) Bridging code fails to check return value of ipv6_dev_get_saddr()
   thus potentially leaving uninitialized garbage in the outgoing ipv6
   header.  From Ulrich Weber.

8) Due to rounding and a reversed operation on jiffies, bridge message
   ages can go backwards instead of forwards, thus breaking STP.  Fixes
   from Joakim Tjernlund.

9) r8169 modifies Config* registers without properly holding the
   Config9346 lock, resulting in corrupted IP fragments on some chips.
   Fix from Francois Romieu.

10) NET_PACKET_ENGINE default wan't set properly during the network
   driver mega-move.  Fix from Stephen Hemminger.

11) vmxnet3 uses TCP header size where it actually should use the UDP
   header size, fix from Shreyas Bhatewara.

12) Netfilter bridge module autoload is busted in the compat case, fix
   from Florian Westphal.

13) Wireless Key removal was not setting multicast bits correctly thus
   accidently killing the unicast key 0 and thus all traffic stops.
   Fix from Johannes Berg.

14) Fix endless retries of A-MPDU transmissions in brcm80211 driver.
