[dpdk-dev] [PATCH v4 06/19] net/hinic: add unicast and multicast MAC set

[Xiaoyun wang <cloud.wangxiaoyun@huawei.com>]

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.
