Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from David Miller:
"This is mostly to fix the iwlwifi regression:
1) Flush GRO state properly in iwlwifi driver, from Alexander Lobakin.
2) Validate TIPC link name with properly length macro, from John
Rutherford.
3) Fix completion init and device query timeouts in ibmvnic, from
Thomas Falcon.
4) Fix SKB size calculation for netlink messages in psample, from
Nikolay Aleksandrov.
5) Similar kind of fix for OVS flow dumps, from Paolo Abeni.
6) Handle queue allocation failure unwind properly in gve driver, we
could try to release pages we didn't allocate. From Jeroen de
Borst.
7) Serialize TX queue SKB list accesses properly in mscc ocelot
driver. From Yangbo Lu"
