[vlan] Expose vlan_find() to network card drivers

Browse Source 
Some network cards automatically strip the VLAN header, providing the
VLAN tag via a side channel such as a completion queue entry.  These
cards need to be able to report receive completions directly against
the relevant VLAN device.
