well, it works fine on the 82598 (heavily tested and used in
production here) but seems to be broken on the 82599. it is either a
hardware bug on the 82599 or related to the fact that it uses slighlty
different advanced descriptors. this should be a more accurate
workaround for now (until we're able to fix it on the 82599):
#if NVLAN > 0
if (hw->mac.type == ixgbe_mac_82598EB)
ifp->if_capabilities |= IFCAP_VLAN_HWTAGGING;
#endif
