I'm trying to get one of these cards (Cyclom-32Y) up and working under
either the cy or cyb drivers and 2.1R.
Brian's web page advertises the fact that several sites are using this driver
in a 'production' environment, but Brian is impossible to nail down to work
on the problem.
The 'cy' driver is not necessarily known to work with this card...
If _anyone_ out there has one of these cards working, I'd love to hear
from you; I don't want to bore the list to death just yet with gory details
when I can't be sure that we're not doing something trivial and stupid.
I just hacked this together. Please notice that you need a config line
# Allow 32 port cyclades boards
options "CY_MAX_CD1400s=8"
to enable 32 ports. You can't put more than one 32 port board in, and you
can't use the same kernel for configurations with multiple smaller boards,
as there are not enough minor numbers available.
I have been running this in production for 2 days so don't expect too much
for stability. It crashed once during that time, but it did not generate a
core dump. I don't know yet whether it is related to cy patches or just
ordinary every couple-of-days panic most freebsd systems here do all the
time, as the load is quite low for holidays.
