We were basicly using the same driver, and he apparently was able to send the packet that I was unable to, but I don't remeber him providing logs that the packet matched exactly what I was sending... (ethernet mac and all)... The ethernet issue is that apparently the MAC hits both an underrun (on an 80 byte packet while 1500 byte nfs writes clear fine) and a loss of CRS durning the preamble... It's likely that there is some special non-ethernet MAC setting that could be messing things up that NetBSD sets much earlier in boot, and we aren't setting, but tracking down what that setting is won't be easy... > Hm.

I'm willing to help someone, but short of having the vendor(s) be truely insterested in solving the ethernet issue, I'd be careful... I did have a request in to Cirrus a long time ago, but I can't seem to log in to see the status.. -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."
