Also make sure to update TSO capability whenever jumbo frame is configured. While I'm here remove unnecessary check of VLAN hardware checksum offloading. vlan(4) already takes care of this. r204230: Remove Tx mbuf parsing code for VLAN in TSO path. Controller does not support TSO over VLAN if VLAN hardware tagging is disabled so there is no need to check VLAN here.
