Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) Fix checksumming regressions, from Tom Herbert. 2) Undo unintentional permissions changes for SCTP rto_alpha and rto_beta sysfs knobs, from Denial Borkmann. 3) VXLAN, like other IP tunnels, should advertize it's encapsulation size using dev->needed_headroom instead of dev->hard_header_len. From Cong Wang. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: net: sctp: fix permissions for rto_alpha and rto_beta knobs vxlan: Checksum fixes net: add skb_pop_rcv_encapsulation udp: call __skb_checksum_complete when doing full checksum net: Fix save software checksum complete net: Fix GSO constants to match NETIF flags udp: ipv4: do not waste time in __udp4_lib_mcast_demux_lookup vxlan: use dev->needed_headroom instead of dev->hard_header_len MAINTAINERS: update cxgb4 maintainer
