Subject: [PATCH net-next] net: hinic: Add support for configuration of rx-vlan-filter by ethtool
Date:   Mon, 31 Oct 2022 15:47:03 +0800
Message-Id: <20221031074715.44224-1-cai.huoqing@linux.dev>

Precedence: bulk

When ethtool config rx-vlan-filter: 'ethtool -K ethx rx-vlan-filter on/off'
to turn on/off the vlan filter, the driver will send control command to firmware,
then set to hardware in this patch.
