The Debian install program reported that options weren't available.   
Where do I find the module options?

Spooky -- just what I'd expect from networking. :-)

I tried ping'ing eth1 from an attached machine, which reported "16  
packets transmitted, 0 packets received, 100% packet loss".

I again looked at /proc/net/dev and found the 37 had increased to 53 --  
but the 2 was still 2.

And /proc/interrupts then showed 55 interrupts for eth1.  (The 53 plus  
2, I take it.)

Is this a module option?

Thanks again!
