The SIMPLEX flag is entirely hardware.
There are some flags which tell the OS how to treat the adapter.
They can be changed by buying a new adapter ......

SIMPLEX means, that the adapter cant hear himself talk during his
transmissions.
I have seen some obscure and dated IBM adapters which where able to listen
while transmitting - there is the choice between ECHO and NOECHO.

On ethernet the signal is quenched; on token rings it comes arround again -
I think simplex is reminding you on this fact.

All current ethernet adapters should show SIMPLEX, I guess.

On AIX I can see the actual media speed via netstat -v.
