how come re(4) does not support gigabit ifconfig option (1000basetx)?

[Tomaž Borštnar <tomaz.borstnar@xxxxxxxx>]

Hello!

	I have one machine with re(4) on board running freebsd 5.stable/amd64 
and another with added re(4) card running DFly-stable (as of 26jan2005). 
First machine has no problem with setting 1000BaseTX, while Dfly gives 
me errors:

web2# ifconfig re0 media 1000basetx mediaopt full-duplex
ifconfig: SIOCSIFMEDIA: Device not configured

dmesg give the answer:
re0: <RealTek 8169S Single-chip Gigabit Ethernet> port 0xb400-0xb4ff mem 
0xfb801
000-0xfb8010ff irq 10 at device 2.0 on pci2

No 1000BaseTX support present :(
