Merge branch 'net-Use-__vlan_hwaccel_-helpers'
Michał Mirosław says:
====================
net: Use __vlan_hwaccel_*() helpers
This series removes from networking core and driver code an assumption
about how VLAN tag presence is stored in an skb. This will allow to free
up overloading of VLAN.CFI bit to incidate tag's presence.
====================
