[dpdk-dev] [PATCH v6 09/15] net/hinic/base: add context and work queue support

[Ziyang Xuan <xuanziyang2@huawei.com>]

Work queue is used for cmdq and tx/rx buff description.
Nic business needs to configure cmdq context and txq/rxq
context. This patch adds data structures and function codes
for work queue and context.
