Subject: [PATCH V2 net-next 02/10] net: hns3: Set extra mac address of pause param for HW

From: Fuyun Liang <liangfuyun1@...wei.com>

The extra mac address of pause param is used to do double check
for pause frame. This patch set it to HW. If we do not do that,
pfc pause frame will be transferred protocol stack when normal
flow control mode is enabled.
