[5/6] net/hns3: fix operating queue when TCAM table is invalid
Checks
Commit Message
From: Huisong Li <lihuisong@huawei.com>
Reset queues will query the TCAM table. The table is cleared after global
or imp reset. Currently, PF driver first resets Rx/Tx queues and then
restore the table during the reset recovery process, which will fail to
query the table and trigger a RAS error.
Fixes: fa29fe45a7b4 ("net/hns3: support queue start and stop")
