netfilter: bridge: pass L2 header and VLAN as netlink attributes in queues to userspace
- This creates 2 netlink attribute NFQA_VLAN and NFQA_L2HDR.
- These are filled up for the PF_BRIDGE family on the way to userspace.
- NFQA_VLAN is a nested attribute, with the NFQA_VLAN_PROTO and the
NFQA_VLAN_TCI carrying the corresponding vlan_proto and vlan_tci
fields from the skb using big endian ordering (and using the CFI
bit as the VLAN_TAG_PRESENT flag in vlan_tci as in the skb)
