Rtl 8139 force 100/FD?

[Pekka Savola]

Hello all,

I have had a couple of Allied Telesyn RTL8139 NIC's for over half a year now,
but they keep losing their 100/FD state now and then.  My driver version
at the moment is 1.08.

Is there any way to force RTL8139 to 100mbit/s Full-duplex?  Full-duplex is
an easy thing (options rtl8139 full_duplex=1), but trying to disable
auto-negotiation and use only 100mbit/s with options=XX like with many,
many other
cards doesn't seem to help any.

By the way, in my NIC both 10 and 100mbit/s LEDS are alight at the same time.
I have forced my NIC to 100/FD with a dos utility diskette, but it seems as
soon as I load the linux driver, the 10 mbit/s LED light to accompany
already-lighted 100 mbit/s.

Anyone noticed something like this?

I have an identical card cross-overed to a Windows box, and it seems to act 
nicely.
