Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) Various TCP control block fixes, including one that crashes with SELinux, from David Ahern and Eric Dumazet. 2) Fix ACK generation in rxrpc, from David Howells. 3) ipvlan doesn't set the mark properly in the ipv4 route lookup key, from Gao Feng. 4) SIT configuration doesn't take on the frag_off ipv4 field configuration properly, fix from Hangbin Liu. 5) TSO can fail after device down/up on stmmac, fix from Lars Persson. 6) Various bpftool fixes (mostly in JSON handling) from Quentin Monnet. 7) Various SKB leak fixes in vhost/tun/tap (mostly observed as performance problems). From Wei Xu. 8) mvpps's TX descriptors were not zero initialized, from Yan Markman. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (57 commits) tcp: use IPCB instead of TCP_SKB_CB in inet_exact_dif_match() tcp: add tcp_v4_fill_cb()/tcp_v4_restore_cb() rxrpc: Fix the MAINTAINERS record rxrpc: Use correct netns source in rxrpc_release_sock() liquidio: fix incorrect indentation of assignment statement stmmac: reset last TSO segment size after device open ipvlan: Add the skb->mark as flow4's member to lookup route s390/qeth: build max size GSO skbs on L2 devices s390/qeth: fix GSO throughput regression s390/qeth: fix thinko in IPv4 multicast address tracking tap: free skb if flags error tun: free skb in early errors vhost: fix skb leak in handle_rx() bnxt_en: Fix a variable scoping in bnxt_hwrm_do_send_msg() bnxt_en: fix dst/src fid for vxlan encap/decap actions bnxt_en: wildcard smac while creating tunnel decap filter bnxt_en: Need to unconditionally shut down RoCE in bnxt_shutdown phylink: ensure we take the link down when phylink_stop() is called sfp: warn about modules requiring address change sequence sfp: improve RX_LOS handling ...
