Pull networking fixes from David Miller:
 "Mostly small bits scattered all over the place, which is usually how
  things go this late in the -rc series.

   1) Proper driver init device resets in bnx2, from Baoquan He.

   2) Fix accounting overflow in __tcp_retransmit_skb(),
      sk_forward_alloc, and ip_idents_reserve, from Eric Dumazet.

   3) Fix crash in bna driver ethtool stats handling, from Ivan Vecera.

   4) Missing check of skb_linearize() return value in mac80211, from
      Johannes Berg.

   5) Endianness fix in nf_table_trace dumps, from Liping Zhang.

   6) SSN comparison fix in SCTP, from Marcelo Ricardo Leitner.

   7) Update DSA and b44 MAINTAINERS entries.

   8) Make input path of vti6 driver work again, from Nicolas Dichtel.

   9) Off-by-one in mlx4, from Sebastian Ott.

  10) Fix fallback route lookup handling in ipv6, from Vincent Bernat.

  11) Fix stack corruption on probe in qed driver, from Yuval Mintz.

  12) PHY init fixes in r8152 from Hayes Wang.

  13) Missing SKB free in irda_accept error path, from Phil Turnbull"
