I would like the ipro100 driver to automatically detect 100M. I have a 20M connection that works at 20M with Linux and Windows on the exact same machine.  Haiku connects at 10Mb and I get 5Mb max transfers.  Not bad at all but I would like to get 20Mb transfers. 

I tried:
>ifconfig /dev/net/ipro100/0 media 100baseTX
ifconfig: Setting media failed: Operation not supported

Finally below is the syslog showing the 10M speed.
