(i.e. name, model number, etc.) There is some trickery in the NetBSD driver that involves "Vortex-based (3c59x pci, eisa) and Boomerang (3c900)" which allow FDDI-sized 4500 byte packets. According to the NetBSD driver's comments, these cards commands dealing with sizes (such as setting threshold, for example) upshift the size value by 2 bits in order to accomodate the full-size packet length (because the 11bits usually provided to store the command argument isn't enough to span the full length). If this may indeed be a problem, we can try right (down) shifting all the ORed in length values by 2 bits, thus expecting the card to interpret the lengths as whatever the value we or'ed in is << 2. If you have one of these cards, let me know and I'll send you a diff off-list. Regards, Bosko. Dan Debertin wrote: > Okay, one more clue.
