Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: "Several small fixes here: 1) Don't crash in tg3 driver when the number of tx queues has been configured to be different from the number of rx queues. From Thadeu Lima de Souza Cascardo. 2) VLAN filter not disabled properly in promisc mode in ixgbe driver, from Vlad Yasevich. 3) Fix OOPS on dellink op in VTI tunnel driver, from Xin Long. 4) IPV6 GRE driver WCCP code checks skb->protocol for ETH_P_IP instead of ETH_P_IPV6, whoops. From Yuri Chislov. 5) Socket matching in ping driver is buggy when packet AF does not match socket's AF. Fix from Jane Zhou. 6) Fix checksum calculation errors in VXLAN due to where the udp_tunnel6_xmit_skb() helper gets it's saddr/daddr from. From Alexander Duyck. 7) Fix 5G detection problem in rtlwifi driver, from Larry Finger. 8) Fix NULL deref in tcp_v{4,6}_send_reset, from Eric Dumazet. 9) Various missing netlink attribute verifications in bridging code, from Thomas Graf. 10) tcp_recvmsg() unconditionally calls ipv4 ip_recv_error even for ipv6 sockets, whoops. Fix from Willem de Bruijn" * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (29 commits) net-timestamp: make tcp_recvmsg call ipv6_recv_error for AF_INET6 socks bridge: Sanitize IFLA_EXT_MASK for AF_BRIDGE:RTM_GETLINK bridge: Add missing policy entry for IFLA_BRPORT_FAST_LEAVE net: Check for presence of IFLA_AF_SPEC net: Validate IFLA_BRIDGE_MODE attribute length bridge: Validate IFLA_BRIDGE_FLAGS attribute length stmmac: platform: fix default values of the filter bins setting net/mlx4_core: Limit count field to 24 bits in qp_alloc_res net: dsa: bcm_sf2: reset switch prior to initialization net: dsa: bcm_sf2: fix unmapping registers in case of errors tg3: fix ring init when there are more TX than RX channels tcp: fix possible NULL dereference in tcp_vX_send_reset() rtlwifi: Change order in device startup rtlwifi: rtl8821ae: Fix 5G detection problem Revert "netfilter: conntrack: fix race in __nf_conntrack_confirm against get_next_corpse" vxlan: Fix boolean flip in VXLAN_F_UDP_ZERO_CSUM6_[TX|RX] ip6_udp_tunnel: Fix checksum calculation net-timestamp: Fix a documentation typo net/ping: handle protocol mismatching scenario af_packet: fix sparse warning ...
