Forcing 3c905 into halfduplex?

[Hadmut Danisch <hadmut.danisch@xxxxxxxxxxxxxxxxxxxxx>]

Hi,

I just have some trouble with a 3c905
(Dell Optiplex PC with 3c905 in motherboard)
and a CenterCom hub  (Linux 2.4.12).

The hub doesn't stand full duplex, but the
3c905 always goes into full duplex when 
using 100 MBit. 

The module parameters allow forcing into
full duplex, but is there a way to force
into half duplex?

regards
Hadmut
