[dpdk-dev] [PATCH v3 06/19] net/hinic: add unicast and multicast MAC set

Xiaoyun wang cloud.wangxiaoyun at huawei.com
Mon Sep 30 16:00:44 CEST 2019


This patch adds unicast and multicast set interfaces.
Application can add or remove unicast MAC address, also can set
multicast MAC address, tha maximum multicast list size is 2048.
