netfilter: nftables_offload: VLAN id needs host byteorder in flow dissector
The flow dissector representation expects the VLAN id in host byteorder. Add the NFT_OFFLOAD_F_NETWORK2HOST flag to swap the bytes from nft_cmp. Fixes: a82055af5959 ("netfilter: nft_payload: add VLAN offload support") Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
