From: Huisong Li <lihuis...@huawei.com> Currently, base and nb_queue in the tc_rxq and tc_txq information of queue and TC mapping on both TX and RX paths are uint8_t. However, these data will be truncated when queue number under a TC is greater than 256. So it is necessary for base and nb_queue to change from uint8_t to uint16_t.
