I know, at the time I did this Chris Leech the Linux developer was having trouble with an interrupt design, so I figured I'd not bang my head against the wall unnecessarily and follow what he was doing :) Since then however, work has been done and particularly with the CB2 support I believe Linux now does use interrupts, so if I go back and rework the driver I will try and follow that path. There is a goodly amount of work to do this justice, and I have been busy with new NIC hardware so much lately, but I hope to come up for air soon so I will try and get this off the queue :) Cheers, Jack > > The driver needs updating and polishing yet, but interest being what it was > > it hasn't been a real high priority. _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
