Merge branch 'Remove-VLAN-CFI-overload'

Michał Mirosław says:

====================
Remove VLAN.CFI overload

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.
