Florian Westphal 8312923739 netfilter: nft_payload: rebuild vlan header on h_proto access 
[ Upstream commit af84f9e447a65b4b9f79e7e5d69e19039b431c56 ]

nft can perform merging of adjacent payload requests.
This means that:

ether saddr 00:11 ... ether type 8021ad ...

is a single payload expression, for 8 bytes, starting at the
ethernet source offset.

Check that offset+length is fully within the source/destination mac
addersses.

This bug prevents 'ether type' from matching the correct h_proto in case
vlan tag got stripped.

Fixes: de6843be3082 ("netfilter: nft_payload: rebuild vlan header when needed")
