[dpdk-dev] [PATCH V3 3/4] doc: announce modified field in DCB TC queue mapping

[Min Hu (Connor)]

From: Huisong Li <lihuisong at huawei.com>

Field type of base and nb_queue will be modified from uint8_t
to uint16_t  in struct "rte_eth_dcb_tc_queue_mapping". As the
data of uint8_t will be truncated when queue number under a TC
is greater than 256.
