[dpdk-dev] [PATCH v3 05/19] net/hinic: add allmulticast mode and MTU set

Xiaoyun wang cloud.wangxiaoyun at huawei.com
Mon Sep 30 16:00:43 CEST 2019


When enable allmulticast mode, all multicast packets
can be received. This patch also adds support for mtu set,
the range of MTU is from 256 to 9600.
