D-Link 528(T) Gigabit support

[Gary Allan <dragonfly@xxxxxxxxxxxxxxx>]

Hello,

Attached is a patch to support the D-Link 528(T) Gigabit cards under 
DragonFly. They are based on the RealTek 8169S chipset and are supported 
by the re(4) driver under FreeBSD 5.4 and above.

The cards are now detected as re(4) devices and have been working 
reliably however I can only get them to operate at 10/100 speeds. Under 
Linux2.6 and FreeBSD 6 I have used them at their full 1000M.

I think it's a mii issue as rgephy.c in not the DragonFly mii_layer 
repository and this file appears to support the 8169S/8110S chipsets. 
Can somebody point me in the right direction to get them working as 
Gigabit cards? Is it just a case of also importing rgephy.c or am I 
missing something?

Regards

G.Allan
