The purpose here is to avoid ptp4l fail due to this condition: timed out while polling for tx timestamp increasing tx_timestamp_timeout may correct this issue, but it is likely caused by a driver bug port 1: send peer delay request failed So either reset the switch before the management frame was sent, or after it was timestamped as well, but not in the middle. The condition may arise either due to a true timeout (i.e. because re-uploading the static config takes time), or due to the TX timestamp actually getting lost due to reset. For the former we can increase tx_timestamp_timeout in userspace, for the latter we need this patch. Locking all traffic during switch reset does not make sense at all, though. Forcing all CPU-originated traffic to potentially block waiting for a sleepable context to send > 800 bytes over SPI is not a good idea. Flows that are autonomously forwarded by the switch will get dropped anyway during switch reset no matter what. So just let all other CPU-originated traffic be dropped as well.
