Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: "The iwlwifi firmware compat fix is in here as well as some other stuff: 1) Fix request socket leak introduced by BPF deadlock fix, from Eric Dumazet. 2) Fix VLAN handling with TXQs in mac80211, from Johannes Berg. 3) Missing __qdisc_drop conversions in prio and qfq schedulers, from Gao Feng. 4) Use after free in netlink nlk groups handling, from Xin Long. 5) Handle MTU update properly in ipv6 gre tunnels, from Xin Long. 6) Fix leak of ipv6 fib tables on netns teardown, from Sabrina Dubroca with follow-on fix from Eric Dumazet. 7) Need RCU and preemption disabled during generic XDP data patch, from John Fastabend" * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (54 commits) bpf: make error reporting in bpf_warn_invalid_xdp_action more clear Revert "mdio_bus: Remove unneeded gpiod NULL check" bpf: devmap, use cond_resched instead of cpu_relax bpf: add support for sockmap detach programs net: rcu lock and preempt disable missing around generic xdp bpf: don't select potentially stale ri->map from buggy xdp progs net: tulip: Constify tulip_tbl net: ethernet: ti: netcp_core: no need in netif_napi_del davicom: Display proper debug level up to 6 net: phy: sfp: rename dt properties to match the binding dt-binding: net: sfp binding documentation dt-bindings: add SFF vendor prefix dt-bindings: net: don't confuse with generic PHY property ip6_tunnel: fix setting hop_limit value for ipv6 tunnel ip_tunnel: fix setting ttl and tos value in collect_md mode ipv6: fix typo in fib6_net_exit() tcp: fix a request socket leak sctp: fix missing wake ups in some situations netfilter: xt_hashlimit: fix build error caused by 64bit division netfilter: xt_hashlimit: alloc hashtable with right size ...
