please, is this checksumming capability supported on NetBSD? I remember Jason
Thorpe saying that even if Intel's 100 Mbit cards (fxp) can do it, intel
hasn't released the documentation and so it's not supported. Are you
sure that the wm driver in NetBSD can do it? The wm(4) manpage doesn't
mention checksumming at all.
