And indeed we tend to have RX overrun problem with this driver.  I can
easily blow my Origin off the net by just floodpinging it for a few
seconds.  In such a case the IOC3 will deactivate RX and signal an
interrupt.  The driver handles this by trying to reinitialize everything
but somehow this often doesn't work.  It also print a message, so you
may want to check syslog / dmesg for kernel messages.  I've once again
starred for a while on the driver code but nothing obvious.
