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.
