[dpdk-dev] [PATCH v3 15/22] net/hns3: add support for hns3 VF PMD driver

["Wei Hu (Xavier)" <xavier.huwei@huawei.com>]

This patch adds support for hns3 VF PMD driver.

In current version, we only support VF device is bound to vfio_pci or
igb_uio and then driven by DPDK driver when PF is driven by kernel mode
hns3 ethdev driver, VF is not supported when PF is driven by DPDK
driver.
