We've been working on tweaking our new
Supermicro Core 2 Duo servers (the same
ones we had the infamouns IPMI port issue
with a few weeks ago (thanks again to all
who helped, esp. Jon Peatfield!)).

Anyway, I find parameters that seem to
require ifconfig to tweak (txqueuelen)
and parameters that seem to need changing
via /etc/modprobe.conf (RxDescriptors,
TxDescriptors).  Is there a single way
to handle both sets?  I haven't tried
txqueuelen in the modprobe.conf file,
but RxDescriptorson the ifconfig line
just barfed.

I found an IBM RedPaper on RHEL tuning
that helped a lot with network tuning in
general, but I haven't found the answer
to this one anywhere.

Thanks,
Miles
