[dpdk-dev] [PATCH 5/5] net/hns3: fix promiscuous mode for PF

[Wei Hu (Xavier)]

From: Chengchang Tang <tangchengchang at huawei.com>

Currently, when promiscuous mode is enabled, it is just allowed to accept
all the unicast and broadcast packets in hns3 PF PMD driver. It should
also be able to receive multicast packets.

Fixes: 19a3ca4c99cf ("net/hns3: add start/stop and configure operations")
