So I made us start setting the mac filter at open time and the problem 
still happened.  I"ve been running down what is going on since then and 
it seems there is a timing window between setting the receive filters 
and the card actually honoring the settings.  I've now gotten to the 
point that it works if I set the receive filters and then reset the 
interface and then set the mac filter.  This is horrible, and I may be 
able to get it to work less horribly but it feels more and more like my 
option is the least painful way.  I'll get it working as cleanly as 
possible and send that patch out and you can decide which approach you 
hate the least.  Thanks,

Josef
