[dpdk-dev] [PATCH 5/7] net/hns3: fix the check for VMDq mode

["Min Hu (Connor)" <humin29@huawei.com>]

From: Huisong Li <lihuisong@huawei.com>

HNS3 PF driver only supports RSS, DCB or NONE multiple queues mode.
Currently, driver doesn't verify the VMDq multi-queue mode completely.
This patch fixes the verification for VMDq mode.

Fixes: 62e3ccc2b94c ("net/hns3: support flow control")
