Please find attached my attempt to import support for the RealTek
8169S/8110S from FreeBSD. This supports my DLink 528(T) Card. Could
someone please review/test? The patch is against HEAD. I ran into two
main issues.

DragonFly is missing a mii_phy_update() function so I wrote an
rge_phy_update() replacement. I'm not sure this is 100% correct.

The card would not auto-negotiate a 1Gbit connection. I increased the
auto-negotiation interval to 17 seconds from five which solved the
problem. There was PR report with this problem and solution for re(4)
and a Cisco switch but I can no longer find the link.

I can see why the cards are $12. I'm slightly disappointed that two of
these cards back to back only manage ~150Mbit/s but it's an improvement
over my built-in vr0.
