[PATCH net-next 0/6] Remove VLAN.CFI overload

[Michał Mirosław]

Fix BPF code/JITs to allow for separate VLAN_PRESENT flag
storage and finally move the flag to separate storage in skbuff.

This is final step to make CLAN.CFI transparent to core Linux
networking stack.

An #ifdef is introduced temporarily to mark fragments masking
VLAN_TAG_PRESENT. This is removed altogether in the final patch.
