Pyun,
I applied the patch, but it didn't attach initially, I added an extra
entry to re_hwrevs as that seemed to be what was missing and it
attached and seems to function (as far as a quick ping test and make
update). Changes I made to if_re.c attached. If you have anything to
try for MSI-X I can probably test those.

Thanks,
Andrew
