Subject: [dpdk-dev] [RFC]lib/ethdev: fix data type in tc_rxq and tc_txq
Date: Sat, 8 Aug 2020 09:09:23 +0800
Message-ID: <fe86002a-87af-8795-d638-d9776545b86d@huawei.com> (raw)

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.
The structure is as follows:

struct rte_eth_dcb_tc_queue_mapping {
     /** rx queues assigned to tc per Pool */
     struct {
         uint8_t base;
         uint8_t nb_queue;
     /** rx queues assigned to tc per Pool */
     struct {
         uint8_t base;
         uint8_t nb_queue;

However, these datas will be truncated when queue number under a TC
is greater than 256. So it is necessay for data type of base and
nb_queue to change from uint8_t to uint16_t.
