Subject: [PATCH net-next 0/6] 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.

Michał Mirosław (6):
  net/skbuff: add macros for VLAN_PRESENT bit
  net/bpf: split VLAN_PRESENT bit handling from VLAN_TCI
  net/bpf_jit: MIPS: split VLAN_PRESENT bit handling from VLAN_TCI
  net/bpf_jit: PPC: split VLAN_PRESENT bit handling from VLAN_TCI
  net/bpf_jit: SPARC: split VLAN_PRESENT bit handling from VLAN_TCI
  net: remove VLAN_TAG_PRESENT
