Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller:
1) Various netfilter fixlets from Pablo and the netfilter team.
2) Fix regression in IPVS caused by lack of PMTU exceptions on local
routes in ipv6, from Julian Anastasov.
3) Check pskb_trim_rcsum for failure in DSA, from Zhouyang Jia.
4) Don't crash on poll in TLS, from Daniel Borkmann.
5) Revert SO_REUSE{ADDR,PORT} change, it regresses various things
including Avahi mDNS. From Bart Van Assche.
6) Missing of_node_put in qcom/emac driver, from Yue Haibing.
7) We lack checking of the TCP checking in one special case during SYN
receive, from Frank van der Linden.
8) Fix module init error paths of mac80211 hwsim, from Johannes Berg.
9) Handle 802.1ad properly in stmmac driver, from Elad Nachman.
10) Must grab HW caps before doing quirk checks in stmmac driver, from
Jose Abreu.
