Pablo Neira Ayuso 5445819e76 netfilter: nft_payload: support for inner header matching / mangling
[ Upstream commit c46b38dc8743535e686b911d253a844f0bd50ead ]

Allow to match and mangle on inner headers / payload data after the
transport header. There is a new field in the pktinfo structure that
stores the inner header offset which is calculated only when requested.
Only TCP and UDP supported at this stage.
