Subject: [PATCH V2 net-next 07/12] net: hns3: not reset TQP in the DOWN while VF resetting
Date: Wed, 24 Apr 2019 19:05:26 +0800 [thread overview]
Message-ID: <1556103931-64031-8-git-send-email-tanhuazhong@huawei.com> (raw)
In-Reply-To: <1556103931-64031-1-git-send-email-tanhuazhong@huawei.com>
Since the hardware does not handle mailboxes and the hardware
reset include TQP reset, so it is unnecessary to reset TQP
in the hclgevf_ae_stop() while doing VF reset. Also it is
unnecessary to reset the remaining TQP when one reset fails.
