Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) Fix timeouts with direct mode authentication in mac80211, from Stanislaw Gruszka. 2) Aggregation sessions can deadlock in ath9k, from Felix Fietkau. 3) Netfilter's xt_addrtype doesn't work with ipv6 due to route lookups creating undesirable cache entries, from Florian Westphal. 4) Fix netfilter's ipt_ULOG from generating non-NULL terminated strings. 5) Fix netdev transmit queue crashes in mac80211, from Johannes Berg. 6) Fix copy and paste error in 802.11 stack that broke reporting of 64-bit station tx statistics, from Felix Fietkau. 7) When qlge_probe fails, it leaks the netdev. Fix from Wei Yongjun. 8) SKB control block (where we store the IP options information, amongst other things) must be cleared properly otherwise ICMP sending can crash for IP tunnels. Fix from Eric Dumazet. 9) Verification of Energy Efficient Ether support was coded wrongly, the test was inversed. Fix from Giuseppe CAVALLARO. 10) TCP handles redirects improperly because the wrong flow key is used for the route lookup. From Michal Kubecek. 11) Don't interpret MSG_CMSG_COMPAT from userspace, fix from Andy Lutomirski. 12) The new AF_VSOCK was missing from the lockdep string table, fix from Federico Vaga. 13) be2net doesn't handle checksumming of IP fragments properly, from Somnath Kotur. 14) Fix several bugs in the device address list code that lead to crashes and other misbehaviors. From Jay Vosburgh. 15) Fix ipv6 segmentation handling of fragmented GRE tunnel traffic, from Pravin B Shalr. 16) Fix usage of stale policies in IPSEC layer, from Paul Moore. 17) Fix team driver dump of ports when there are a large number of them, from Jiri Pirko. 18) Fix softlockups in UDP ipv4 socket lookup causes by and error in the hlist_nulls_for_each_entry_rcu() macro. From Eric Dumazet. 19) Fix several regressions added by the high rate accuracy changes to the htb packet scheduler. From Eric Dumazet. 20) Fix DMA'ing onto the stack in esd_usb2 and peak_usb CAN drivers, from Olivier Sobrie and Marc Kleine-Budde. 21) Fix unremovable network devices due to missing route pointer installation in the per-device ipv6 address list entries. From Gao feng. 22) Apply the tg3 5719 DMA workaround on 5720 chips as well, otherwise we get stalls. From Nithin Sujir. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (68 commits) net_sched: htb: do not mix 1ns and 64ns time units net: fix sk_buff head without data area tg3: Add read dma workaround for 5720 net: ethernet: xilinx_emaclite: set protocol selector bits when writing ANAR bnx2x: Fix bridged GSO for 57710/57711 chips net: fec: add fallback to random MAC address bnx2x: fix TCP offload for tunneling ipv4 over ipv6 ipv6: assign rt6_info to inet6_ifaddr in init_loopback net/mlx4_core: Keep VF assigned MAC in the PF admin table net/mlx4_en: Handle unassigned VF MAC address correctly net/mlx4_core: Return -EPROBE_DEFER when a VF is probed before PF is sufficiently initialized net/mlx4_en: Fix adaptive moderation cq update net: can: peak_usb: Do not do dma on the stack net: can: esd_usb2: Do not do dma on the stack net: can: kvaser_usb: fix reception on "USBcan Pro" and "USBcan R" type hardware. net_sched: restore "overhead xxx" handling net: force a reload of first item in hlist_nulls_for_each_entry_rcu hyperv: Fix vlan_proto setting in netvsc_recv_callback() team: fix port list dump for big number of ports list: introduce list_first_entry_or_null ...
