Subject[PATCH] r8152: stop submitting rx for -EPROTO
Date
When unplugging RTL8152 Fast Ethernet Adapter which is plugged
into an USB HUB, the driver would get -EPROTO for bulk transfer.
There is a high probability to get the soft/hard lockup
information if the driver continues to submit Rx before the HUB
completes the detection of all hub ports and issue the
disconnect event.
