Subject: Merge branch 'master' of git://1984.lsi.us.es/nf-next
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=545b29019c8959c805abfe8194d47e989f1a6e5f;p=linux-beck.git

Merge branch 'master' of git://1984.lsi.us.es/nf-next

Conflicts:
	net/ipv6/netfilter/nf_conntrack_l3proto_ipv6.c

Minor conflict due to some IS_ENABLED conversions done
in net-next.
