Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) Fix wrong TCP checksums on MTU probing when checksum offloading is disabled, from Douglas Caetano dos Santos. 2) Fix qdisc backlog updates in qfq and sfb schedulers, from Cong Wang. 3) Route lookup flow key protocol value is wrong in ip6gre_xmit_other(), fix from Lance Richardson. 4) Scheduling while atomic in multicast routing code of ipv4 and ipv6, fix from Nikolay Aleksandrov. 5) Fix packet alignment in fec driver, from Eric Nelson. 6) Fix perf regression in sctp due to struct layout and cache misses, from Xin Long. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: sctp: fix the issue sctp_diag uses lock_sock in rcu_read_lock sctp: change to check peer prsctp_capable when using prsctp polices sctp: remove prsctp_param from sctp_chunk sctp: move sent_count to the memory hole in sctp_chunk tg3: Avoid NULL pointer dereference in tg3_io_error_detected() act_ife: Fix false encoding act_ife: Fix external mac header on encode VSOCK: Don't dec ack backlog twice for rejected connections Revert "net: ethernet: bcmgenet: use phydev from struct net_device" net: fec: align IP header in hardware net: fec: remove QUIRK_HAS_RACC from i.mx27 net: fec: remove QUIRK_HAS_RACC from i.mx25 ipmr, ip6mr: fix scheduling while atomic and a deadlock with ipmr_get_route ip6_gre: fix flowi6_proto value in ip6gre_xmit_other() tcp: fix a compile error in DBGUNDO() tcp: fix wrong checksum calculation on MTU probing sch_sfb: keep backlog updated with qlen sch_qfq: keep backlog updated with qlen can: dev: fix deadlock reported after bus-off
