Subject: [PATCH V4 for-next 13/14] RDMA/hns: Disable alw_lcl_lpbk of SSU
Date: Thu, 8 Aug 2019 22:53:53 +0800 [thread overview]
Message-ID: <1565276034-97329-14-git-send-email-oulijun@huawei.com> (raw)
In-Reply-To: <1565276034-97329-1-git-send-email-oulijun@huawei.com>
From: Weihang Li <liweihang@hisilicon.com>
If we enabled alw_lcl_lpbk in promiscuous mode, packet whose source
and destination mac address is equal will be handled in both inner
loopback and outer loopback. This will halve performance of roce in
promiscuous mode.
