Pull networking fixes from David Miller: 1) Various ipvlan fixes from Eric Dumazet and Mahesh Bandewar. The most important is to not assume the packet is RX just because the destination address matches that of the device. Such an assumption causes problems when an interface is put into loopback mode. 2) If we retry when creating a new tc entry (because we dropped the RTNL mutex in order to load a module, for example) we end up with -EAGAIN and then loop trying to replay the request. But we didn't reset some state when looping back to the top like this, and if another thread meanwhile inserted the same tc entry we were trying to, we re-link it creating an enless loop in the tc chain. Fix from Daniel Borkmann. 3) There are two different WRITE bits in the MDIO address register for the stmmac chip, depending upon the chip variant. Due to a bug we could set them both, fix from Hock Leong Kweh. 4) Fix mlx4 bug in XDP_TX handling, from Tariq Toukan. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: net: stmmac: fix incorrect bit set in gmac4 mdio addr register r8169: add support for RTL8168 series add-on card. net: xdp: remove unused bfp_warn_invalid_xdp_buffer() openvswitch: upcall: Fix vlan handling. ipv4: Namespaceify tcp_tw_reuse knob net: korina: Fix NAPI versus resources freeing net, sched: fix soft lockup in tc_classify net/mlx4_en: Fix user prio field in XDP forward tipc: don't send FIN message from connectionless socket ipvlan: fix multicast processing ipvlan: fix various issues in ipvlan_process_multicast()
