enic: Pass 802.1p bits for packets tagged with vlan zero
enic driver currently passes 802.1p bits to the upper layers for packets
tagged with non-zero vlan ids only. This patch extends such behaviour to
zero vlan tagged packets also.
The patch is dependant on the following kernel patches:
1) vlan_dev: VLAN 0 should be treated as "no vlan tag" (802.1p packet)
- net-next-2.6 git commit: ad1afb00393915a51c21b1ae8704562bf036855f
- Available 2.6.36 and later
2) vlan: Centralize handling of hardware acceleration.
- net-next-2.6 git commit: 3701e51382a026cba10c60b03efabe534fba4ca4
- Available 2.6.37 and later
