Pull networking fixes from David Miller: 1) Fix hotplug deadlock in hv_netvsc, from Stephen Hemminger. 2) Fix double-free in rmnet driver, from Dan Carpenter. 3) INET connection socket layer can double put request sockets, fix from Eric Dumazet. 4) Don't match collect metadata-mode tunnels if the device is down, from Haishuang Yan. 5) Do not perform TSO6/GSO on ipv6 packets with extensions headers in be2net driver, from Suresh Reddy. 6) Fix scaling error in gen_estimator, from Eric Dumazet. 7) Fix 64-bit statistics deadlock in systemport driver, from Florian Fainelli. 8) Fix use-after-free in sctp_sock_dump, from Xin Long. 9) Reject invalid BPF_END instructions in verifier, from Edward Cree. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (43 commits) mlxsw: spectrum_router: Only handle IPv4 and IPv6 events Documentation: link in networking docs tcp: fix data delivery rate bpf/verifier: reject BPF_ALU64|BPF_END sctp: do not mark sk dumped when inet_sctp_diag_fill returns err sctp: fix an use-after-free issue in sctp_sock_dump netvsc: increase default receive buffer size tcp: update skb->skb_mstamp more carefully net: ipv4: fix l3slave check for index returned in IP_PKTINFO net: smsc911x: Quieten netif during suspend net: systemport: Fix 64-bit stats deadlock net: vrf: avoid gcc-4.6 warning qed: remove unnecessary call to memset tg3: clean up redundant initialization of tnapi tls: make tls_sw_free_resources static sctp: potential read out of bounds in sctp_ulpevent_type_enabled() MAINTAINERS: review Renesas DT bindings as well net_sched: gen_estimator: fix scaling error in bytes/packets samples nfp: wait for the NSP resource to appear on boot nfp: wait for board state before talking to the NSP ...
