Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) Fix refcounting bug for connections in on-packet scheduling mode of IPVS, from Julian Anastasov. 2) Set network header properly in AF_PACKET's packet_snd, from Willem de Bruijn. 3) Fix regressions in 3c59x by converting to generic DMA API. It was relying upon the hack that the PCI DMA interfaces would accept NULL for EISA devices. From Christoph Hellwig. 4) Remove RDMA devices before unregistering netdev in QEDE driver, from Michal Kalderon. 5) Use after free in TUN driver ptr_ring usage, from Jason Wang. 6) Properly check for missing netlink attributes in SMC_PNETID requests, from Eric Biggers. 7) Set DMA mask before performaing any DMA operations in vmxnet3 driver, from Regis Duchesne. 8) Fix mlx5 build with SMP=n, from Saeed Mahameed. 9) Classifier fixes in bcm_sf2 driver from Florian Fainelli. 10) Tuntap use after free during release, from Jason Wang. 11) Don't use stack memory in scatterlists in tls code, from Matt Mullins. 12) Not fully initialized flow key object in ipv4 routing code, from David Ahern. 13) Various packet headroom bug fixes in ip6_gre driver, from Petr Machata. 14) Remove queues from XPS maps using correct index, from Amritha Nambiar. 15) Fix use after free in sock_diag, from Eric Dumazet. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (64 commits) net: ip6_gre: fix tunnel metadata device sharing. cxgb4: fix offset in collecting TX rate limit info net: sched: red: avoid hashing NULL child sock_diag: fix use-after-free read in __sk_free sh_eth: Change platform check to CONFIG_ARCH_RENESAS net: dsa: Do not register devlink for unused ports net: Fix a bug in removing queues from XPS map bpf: fix truncated jump targets on heavy expansions bpf: parse and verdict prog attach may race with bpf map update bpf: sockmap update rollback on error can incorrectly dec prog refcnt net: test tailroom before appending to linear skb net: ip6_gre: Fix ip6erspan hlen calculation net: ip6_gre: Split up ip6gre_changelink() net: ip6_gre: Split up ip6gre_newlink() net: ip6_gre: Split up ip6gre_tnl_change() net: ip6_gre: Split up ip6gre_tnl_link_config() net: ip6_gre: Fix headroom request in ip6erspan_tunnel_xmit() net: ip6_gre: Request headroom in __gre6_xmit() selftests/bpf: check return value of fopen in test_verifier.c erspan: fix invalid erspan version. ...
