Well, the number of interrupts per second is really much higher than e.g. with
the fxp driver:
xl driver TX: 13500 intrs/sec
RX: 13800 intrs/sec
fxp driver TX: 5700 intrs/sec
RX: 8500 intrs/sec
David, could you perhaps send me your if_xl* files so I can test your
modifications here?
Thanks & kind regards,
M.
