Hello: This patch was applied to netdev/net.git (refs/heads/master): On Mon, 4 Oct 2021 14:28:58 +0800 you wrote:
For the situation that the disconnect event comes very late when the device is unplugged, the driver would resubmit the RX bulk transfer after getting the callback with -EPROTO immediately and continually. Finally, soft lockup occurs. This patch avoids to resubmit RX immediately. It uses a workqueue to schedule the RX NAPI. And the NAPI would resubmit the RX. It let the disconnect event have opportunity to stop the submission before soft lockup. [...]
