AFAIK 8139C+ provides 8139 compatible mode which doesn't use
descriptor based transfer mechanism. As you know this mode
really sucks and need much more CPU power to saturate the link.
So I don't think it's good idea to make rl(4) serve 8139C+.

However I've seen one user reported re(4) breakage on stable.

that seems to be exactly the problem i initially observed as well.

Please try latest stable and show your results. If it still does not
work please let us know. I don't have 8139C+ based NICs so it would be
