Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller:
"Mostly small sets of driver fixes scattered all over the place.
1) Mediatek driver fixes from Sean Wang. Forward port not written
correctly during TX map, missed handling of EPROBE_DEFER, and
mistaken use of put_page() instead of skb_free_frag().
2) Fix socket double-free in KCM code, from WANG Cong.
3) QED driver fixes from Sudarsana Reddy Kalluru, including a fix for
using the dcbx buffers before initializing them.
4) Mellanox Switch driver fixes from Jiri Pirko, including a fix for
double fib removals and an error handling fix in
mlxsw_sp_module_init().
5) Fix kernel panic when enabling LLDP in i40e driver, from Dave
Ertman.
6) Fix padding of TSO packets in thunderx driver, from Sunil Goutham.
7) TCP's rcv_wup not initialized properly when using fastopen, from
Neal Cardwell.
8) Don't use uninitialized flow keys in flow dissector, from Gao
Feng.
9) Use after free in l2tp module unload, from Sabrina Dubroca.
10) Fix interrupt registry ordering issues in smsc911x driver, from
Jeremy Linton.
11) Fix crashes in bonding having to do with enslaving and rx_handler,
from Mahesh Bandewar.
12) AF_UNIX deadlock fixes from Linus.
13) In mlx5 driver, don't read skb->xmit_mode after it might have been
freed from the TX reclaim path. From Tariq Toukan.
14) Fix a bug from 2015 in TCP Yeah where the congestion window does
not increase, from Artem Germanov.
15) Don't pad frames on receive in NFP driver, from Jakub Kicinski.
16) Fix chunk fragmenting in SCTP wrt. GSO, from Marcelo Ricardo
Leitner.
17) Fix deletion of VRF routes, from Mark Tomlinson.
18) Fix device refcount leak when DAD fails in ipv6, from Wei Yongjun"
