Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from David Miller:
1) Fix interrupt name truncation in mv88e6xxx dsa driver, from Andrew
Lunn.
2) Process generic XDP even if SKB is cloned, from Toke Høiland-Jørgensen.
3) Fix leak of kernel memory to userspace in smc, from Eric Dumazet.
4) Add some missing netlink attribute validation to matchall and
flower, from Davide Caratti.
5) Send icmp responses properly when NAT has been applied to the frame
before we get to the tunnel emitting the icmp, from Jason Donenfeld.
6) Make sure there is enough SKB headroom when adding dsa tags for qca
and ar9331. From Per Forlin.
