Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller: 1) Must perform TXQ teardown before unregistering interfaces in mac80211, from Toke Høiland-Jørgensen. 2) Don't allow creating mac80211_hwsim with less than one channel, from Johannes Berg. 3) Division by zero in cfg80211, fix from Johannes Berg. 4) Fix endian issue in tipc, from Haiqing Bai. 5) BPF sockmap use-after-free fixes from Daniel Borkmann. 6) Spectre-v1 in mac80211_hwsim, from Jinbum Park. 7) Missing rhashtable_walk_exit() in tipc, from Cong Wang. 8) Revert kvzalloc() conversion of AF_PACKET, it breaks mmap() when kvzalloc() tries to use kmalloc() pages. From Eric Dumazet. 9) Fix deadlock in hv_netvsc, from Dexuan Cui. 10) Do not restart timewait timer on RST, from Florian Westphal. 11) Fix double lwstate refcount grab in ipv6, from Alexey Kodanev. 12) Unsolicit report count handling is off-by-one, fix from Hangbin Liu. 13) Sleep-in-atomic in cadence driver, from Jia-Ju Bai. 14) Respect ttl-inherit in ip6 tunnel driver, from Hangbin Liu. 15) Use-after-free in act_ife, fix from Cong Wang. 16) Missing hold to meta module in act_ife, from Vlad Buslov. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (91 commits) net: phy: sfp: Handle unimplemented hwmon limits and alarms net: sched: action_ife: take reference to meta module act_ife: fix a potential use-after-free net/mlx5: Fix SQ offset in QPs with small RQ tipc: correct spelling errors for tipc_topsrv_queue_evt() comments tipc: correct spelling errors for struct tipc_bc_base's comment bnxt_en: Do not adjust max_cp_rings by the ones used by RDMA. bnxt_en: Clean up unused functions. bnxt_en: Fix firmware signaled resource change logic in open. sctp: not traverse asoc trans list if non-ipv6 trans exists for ipv6_flowlabel sctp: fix invalid reference to the index variable of the iterator net/ibm/emac: wrong emac_calc_base call was used by typo net: sched: null actions array pointer before releasing action vhost: fix VHOST_GET_BACKEND_FEATURES ioctl request definition r8169: add support for NCube 8168 network card ip6_tunnel: respect ttl inherit for ip6tnl mac80211: shorten the IBSS debug messages mac80211: don't Tx a deauth frame if the AP forbade Tx mac80211: Fix station bandwidth setting after channel switch mac80211: fix a race between restart and CSA flows ...
