Pull networking fixes from David Miller: 1) Ensure that mtu is at least IPV6_MIN_MTU in ipv6 VTI tunnel driver, from Steffen Klassert. 2) Fix crashes when user tries to get_next_key on an LPM bpf map, from Alexei Starovoitov. 3) Fix detection of VLAN fitlering feature for bnx2x VF devices, from Michal Schmidt. 4) We can get a divide by zero when TCP socket are morphed into listening state, fix from Eric Dumazet. 5) Fix socket refcounting bugs in skb_complete_wifi_ack() and skb_complete_tx_timestamp(). From Eric Dumazet. 6) Use after free in dccp_feat_activate_values(), also from Eric Dumazet. 7) Like bonding team needs to use ETH_MAX_MTU as netdev->max_mtu, from Jarod Wilson. 8) Fix use after free in vrf_xmit(), from David Ahern. 9) Don't do UDP Fragmentation Offload on IPComp ipsec packets, from Alexey Kodanev. 10) Properly check napi_complete_done() return value in order to decide whether to re-enable IRQs or not in amd-xgbe driver, from Thomas Lendacky. 11) Fix double free of hwmon device in marvell phy driver, from Andrew Lunn. 12) Don't crash on malformed netlink attributes in act_connmark, from Etienne Noss. 13) Don't remove routes with a higher metric in ipv6 ECMP route replace, from Sabrina Dubroca. 14) Don't write into a cloned SKB in ipv6 fragmentation handling, from Florian Westphal. 15) Fix routing redirect races in dccp and tcp, basically the ICMP handler can't modify the socket's cached route in it's locked by the user at this moment.
