And then there's the *third* FreeBSD driver, if_gx.c by Jonathan
Lemon. That driver addresses most of the design issues Jason raised
with your driver (some of which I know have been fixed since). The
rxeof and tx routines in if_gx.c look awfully like some of Bill Paul's
FreeBSD drivers, which have already been bus-dma-ified and imported
into NetBSD.
Intel's stance on licensing drivers for their gig-E cards looks just
plain silly, and it can only be hurting them in the marketplace.
Whether they see it that way or not is another story, though :).
