bnx2: Update vlan_features

[PATCH net-next-2.6] bnx2: Update vlan_features

In order to get full use of some advanced features of BNX2, we now need to
fill dev->vlan_features.

Patch successfully tested with vlan devices built on top of bonding.
(bond0 : one bnx2 slave, one tg3 slave (not yet vlan_features enabled)
