1069 * So we have few choises for TX:
1070 * - Use just one TX queue.
1071 * - Allow cksum offload only for one TX queue.
1072 * - Don't allow TX cksum offload at all.
1073 * For now, option #1 was chosen.
1074 * To use second RX queue we have to use extended RX descriptor
1075 * (Multiple Receive Queues are mutually exclusive with UDP
1076 * fragmentation and are not supported when a legacy receive
1077 * descriptor format is used).
1078 * Which means separate RX routinies - as legacy nics (82540, 82545)
1079 * don't support extended RXD.
1080 * To avoid it we support just one RX queue for now (no RSS).
