Backort upstream patch which preserves oif of IPv6 link scoped packets.
The outgoing interface of IPv6 link scope packets can be changed by the
function ip6_route_me_harder. This is unwanted behavior for link local
packets and multicast packets as the outgoing interface is fixed and must
not be altered as it can break neighbor discovery and multicast listener
discovery.

Commit b7265c59ab ("kernel: backport a series of netfilter cleanup
patches to 4.14") added patch 302-netfilter-nf_tables_inet-don-t-use-
multihook-infrast.patch. That patch switches the netfilter core in the
kernel to use the new native NFPROTO_INET support. Unfortunately, the
new native NFPROTO_INET support does not exist in 4.14 and was not
backported along with this patchset. As such, nftables inet tables never
see any traffic.
As an example the following nft counter rule should increment for every
packet coming into the box, but never will:
nft add table inet foo
nft add chain inet foo bar { type filter hook input priority 0\; }
nft add rule inet foo bar counter
This commit pulls in the required backport patches to add the new
native NFPROTO_INET support, and thus restore nftables inet table
functionality.
Tested on Turris Omnia (mvebu)
