Ok, I see your point. A LACP PDU can't be encapsulated in a VLAN packet
anyway, as it is link local traffic. So a check for ol_flags &
PKT_RX_VLAN_PKT != 0 should be sufficient, otherwise if the
PKT_RX_VLAN_PKT flag is true the packet cannot be link local and
therefore a LACP PDU. I think that it's safe to assume all PMDs must set
this flag if VLAN stripping is enabled?
