Pull networking fixes from David Miller: 1) Don't corrupt xfrm_interface parms before validation, from Nicolas Dichtel. 2) Revert use of usb-wakeup in btusb, from Mario Limonciello. 3) Block ipv6 packets in bridge netfilter if ipv6 is disabled, from Leonardo Bras. 4) IPS_OFFLOAD not honored in ctnetlink, from Pablo Neira Ayuso. 5) Missing ULP check in sock_map, from John Fastabend. 6) Fix receive statistic handling in forcedeth, from Zhu Yanjun. 7) Fix length of SKB allocated in 6pack driver, from Christophe JAILLET. 8) ip6_route_info_create() returns an error pointer, not NULL. From Maciej ┼╗enczykowski. 9) Only add RDS sock to the hashes after rs_transport is set, from Ka-Cheong Poon. 10) Don't double clean TX descriptors in ixgbe, from Ilya Maximets. 11) Presence of transmit IPSEC offload in an SKB is not tested for correctly in ixgbe and ixgbevf. From Steffen Klassert and Jeff Kirsher. 12) Need rcu_barrier() when register_netdevice() takes one of the notifier based failure paths, from Subash Abhinov Kasiviswanathan. 13) Fix leak in sctp_do_bind(), from Mao Wenan. * git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (72 commits) cdc_ether: fix rndis support for Mediatek based smartphones sctp: destroy bucket if failed to bind addr sctp: remove redundant assignment when call sctp_get_port_local sctp: change return type of sctp_get_port_local ixgbevf: Fix secpath usage for IPsec Tx offload sctp: Fix the link time qualifier of 'sctp_ctrlsock_exit()' ixgbe: Fix secpath usage for IPsec TX offload. net: qrtr: fix memort leak in qrtr_tun_write_iter net: Fix null de-reference of device refcount ipv6: Fix the link time qualifier of 'ping_v6_proc_exit_net()' tun: fix use-after-free when register netdev failed tcp: fix tcp_ecn_withdraw_cwr() to clear TCP_ECN_QUEUE_CWR ixgbe: fix double clean of Tx descriptors with xdp ixgbe: Prevent u8 wrapping of ITR value to something less than 10us mlx4: fix spelling mistake "veify" -> "verify" net: hns3: fix spelling mistake "undeflow" -> "underflow" net: lmc: fix spelling mistake "runnin" -> "running" NFC: st95hf: fix spelling mistake "receieve" -> "receive" net/rds: An rds_sock is added too early to the hash table mac80211: Do not send Layer 2 Update frame before authorization ...
