DG>    Can you provide us with the output of 'netstat -rna'?

Sure.  I had it in my original, but omitted it from the followup.

I'm running 4.3-STABLE from yesterday afternoon, after the latest fxp
patches.  Same error on 4.2-RELEASE, tho.

Same setup runs fine with two different brands of NICs in another
machine (de0 and sis0)
