Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

Pull networking fixes from David Miller: "It's been a while since my last pull request so quite a few fixes have piled up." Indeed. 1) Fix nf_{log,queue} compilation with PROC_FS disabled, from Pablo Neira Ayuso. 2) Fix data corruption on some tg3 chips with TSO enabled, from Michael Chan. 3) Fix double insertion of VLAN tags in be2net driver, from Sarveshwar Bandi. 4) Don't have TCP's MD5 support pass > PAGE_SIZE page offsets in scatter-gather entries into the crypto layer, the crypto layer can't handle that. From Eric Dumazet. 5) Fix lockdep splat in 802.1Q MRP code, also from Eric Dumazet. 6) Fix OOPS in netfilter log module when called from conntrack, from Hans Schillstrom. 7) FEC driver needs to use netif_tx_{lock,unlock}_bh() rather than the non-BH disabling variants. From Fabio Estevam. 8) TCP GSO can generate out-of-order packets, fix from Eric Dumazet. 9) vxlan driver doesn't update 'used' field of fdb entries when it should, from Sridhar Samudrala. 10) ipv6 should use kzalloc() to allocate inet6 socket cork options, otherwise we can OOPS in ip6_cork_release(). From Eric Dumazet. 11) Fix races in bonding set mode, from Nikolay Aleksandrov. 12) Fix checksum generation regression added by "r8169: fix 8168evl frame padding.", from Francois Romieu. 13) ip_gre can look at stale SKB data pointer, fix from Eric Dumazet. 14) Fix checksum handling when GSO is enabled in bnx2x driver with certain chips, from Yuval Mintz. 15) Fix double free in batman-adv, from Martin Hundebøll. 16) Fix device startup synchronization with firmware in tg3 driver, from Nithin Sujit. 17) perf networking dropmonitor doesn't work at all due to mixed up trace parameter ordering, from Ben Hutchings. 18) Fix proportional rate reduction handling in tcp_ack(), from Nandita Dukkipati. 19) IPSEC layer doesn't return an error when a valid state is detected, causing an OOPS. Fix from Timo Teräs. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (85 commits) be2net: bug fix on returning an invalid nic descriptor tcp: xps: fix reordering issues net: Revert unused variable changes. xfrm: properly handle invalid states as an error virtio_net: enable napi for all possible queues during open tcp: bug fix in proportional rate reduction. net: ethernet: sun: drop unused variable net: ethernet: korina: drop unused variable net: ethernet: apple: drop unused variable qmi_wwan: Added support for Cinterion's PLxx WWAN Interface perf: net_dropmonitor: Remove progress indicator perf: net_dropmonitor: Use bisection in symbol lookup perf: net_dropmonitor: Do not assume ordering of dictionaries perf: net_dropmonitor: Fix symbol-relative addresses perf: net_dropmonitor: Fix trace parameter order net: fec: use a more proper compatible string for MVF type device qlcnic: Fix updating netdev->features qlcnic: remove netdev->trans_start updates within the driver qlcnic: Return proper error codes from probe failure paths tg3: Update version to 3.132 ...
