Did you turn on debug in the driver and try it?
Is there any output at all from the driver now?
I don't see anything explicitly in the driver about cable disconnect.
I do see ne_watchdog which is hooked to if_watchdog. The
associated if_timer value is 2 which I think is 2 seconds based
upon IFNET_SLOWHZ and hz being rtems_bsdnet_ticks_per_second.
But this looks like a Tx timeout and is way shorter than what you
are seeing.
