I am not too sure what impact the pcn driver has in the market but there does seem to be these AMD ethernet interfaces built into plenty of motherboards. It may be reasonable, and very easy, to just remove the pcn driver and then simply use the open source ae driver. The pcn driver is not GLDv3 aware and thus a from scratch re-write is probably needed. I do recall talking with Garrett D'Amore ( an very talented man in such issues ) a long long time ago about this very issue. I am thinking that OpenSolaris certainly uses plenty of open source software in it already so one more driver ( ae ) would certainly not be a great concern. The ae driver is already a GLDv3 smart driver. I better go verify that however. I do recall filing a bug about this also, a long time ago. I can not find it and I guess I'll go refile again and perhaps it will get marked as a duplicate. -- Dennis Clarke dclarke at opensolaris.ca <- Email related to the open source Solaris dclarke at blastwave.org <- Email related to open source for Solaris
