Pull networking fixes from David Miller: 1) Use an appropriate TSQ pacing shift in mac80211, from Toke Høiland-Jørgensen. 2) Just like ipv4's ip_route_me_harder(), we have to use skb_to_full_sk in ip6_route_me_harder, from Eric Dumazet. 3) Fix several shutdown races and similar other problems in l2tp, from James Chapman. 4) Handle missing XDP flush properly in tuntap, for real this time. From Jason Wang. 5) Out-of-bounds access in powerpc ebpf tailcalls, from Daniel Borkmann. 6) Fix phy_resume() locking, from Andrew Lunn. 7) IFLA_MTU values are ignored on newlink for some tunnel types, fix from Xin Long. 8) Revert F-RTO middle box workarounds, they only handle one dimension of the problem. From Yuchung Cheng. 9) Fix socket refcounting in RDS, from Ka-Cheong Poon. 10) Don't allow ppp unit registration to an unregistered channel, from Guillaume Nault. 11) Various hv_netvsc fixes from Stephen Hemminger. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (98 commits) hv_netvsc: propagate rx filters to VF hv_netvsc: filter multicast/broadcast hv_netvsc: defer queue selection to VF hv_netvsc: use napi_schedule_irqoff hv_netvsc: fix race in napi poll when rescheduling hv_netvsc: cancel subchannel setup before halting device hv_netvsc: fix error unwind handling if vmbus_open fails hv_netvsc: only wake transmit queue if link is up hv_netvsc: avoid retry on send during shutdown virtio-net: re enable XDP_REDIRECT for mergeable buffer ppp: prevent unregistered channels from connecting to PPP units tc-testing: skbmod: fix match value of ethertype mlxsw: spectrum_switchdev: Check success of FDB add operation net: make skb_gso_*_seglen functions private net: xfrm: use skb_gso_validate_network_len() to check gso sizes net: sched: tbf: handle GSO_BY_FRAGS case in enqueue net: rename skb_gso_validate_mtu -> skb_gso_validate_network_len rds: Incorrect reference counting in TCP socket creation net: ethtool: don't ignore return from driver get_fecparam method vrf: check forwarding on the original netdevice when generating ICMP dest unreachable ...
