Quoth David:
1) GRO MAC header comparisons were ethernet specific, breaking other
link types. This required a multi-faceted fix to cure the originally
noted case (Infiniband), because IPoIB was lying about it's actual
hard header length. Thanks to Eric Dumazet, Roland Dreier, and
others.
2) Fix build failure when INET_UDP_DIAG is built in and ipv6 is modular.
From Anisse Astier.
3) Off by ones and other bug fixes in netprio_cgroup from Neil Horman.
4) ipv4 TCP reset generation needs to respect any network interface
binding from the socket, otherwise route lookups might give a
different result than all the other segments received. From Shawn
Lu.
5) Fix unintended regression in ipv4 proxy ARP responses, from Thomas
Graf.
6) Fix SKB under-allocation bug in sh_eth, from Yoshihiro Shimoda.
7) Revert skge PCI mapping changes that are causing crashes for some
folks, from Stephen Hemminger.
8) IPV4 route lookups fill in the wildcarded fields of the given flow
lookup key passed in, which is fine most of the time as this is
exactly what the caller's want. However there are a few cases that
want to retain the original flow key values afterwards, so handle
those cases properly. Fix from Julian Anastasov.
9) IGB/IXGBE VF lookup bug fixes from Greg Rose.
10) Properly null terminate filename passed to ethtool flash device
method, from Ben Hutchings.
11) S3 resume fix in via-velocity from David Lv.
12) Fix double SKB free during xmit failure in CAIF, from Dmitry
Tarnyagin.
