I'm not so sure. If I change "mac8390.o" to "mac8390.o 8390.o" in
drivers/net/Makefile, I get some compiler warnings but that's all. (I
didn't try booting it. Also mac8390 is built-in -- apparently it doesn't
do modular).
Yes, but if the NIC works with idle disk and fails with SCSI load,
would you not blame the VIA driver?
Not necessarily - there may be a driver locking out interrupts for too
long so the timeout happens before the interrupt gets serviced. Not very
likely - the timeout would have to run before the net bottom half.
If that were the kind of bug affecting Christian's machine, it seems
unlikely that it would show up on a Mac. But I will add disk I/O to the
stress test and report anything relevant.
I guess there are benefits to each approach? I assume that linking to
8390.o, though simpler, would end up slower (?)
That, and it ends up not using net_ops in the driver at all. Obsolete
interface ...
hydra.c, zorro8390.c, 8390.c and 8390p.c all have have net_device_ops
structs these days. I think everything got converted a year or so back.
