hello
I'm still trying to get the Conexant nic to work. Last time

Now I tried all possible medias, run tulip-diag and ifconfig and noted down
the most relevant info. In brief:
options=0,0 autoselect (default to 10baseT): errors=carrier>0,rx>0,tx=0
options=1,1 10base2: carrier=2*errors,errors>0,rx=tx=0
options=3,3 100baseTx: errors=carrier=rx=0,tx>0
options=6,6 100baseT4: rx=0,tx>0
options=9,9 MII 10baseT:errors=carrier=rx=tx=0 (Tx processing setup info)
options=11,11 MII autoselect:errors=carrier=rx=tx=0 (Tx processing setup info)
options=12,12 Serial 10baseT (no autosel):carrier=2*errors,errors>0,tx=rx=0
options=13,13 MII 100baseTx: errors=carrier=rx=tx=0 (Tx processing setup info)
options=15,15 MII 100baseT4: errors=carrier=rx=tx=0 (Tx processing setup info)
based on 'ifconfig eth0' and 'tulip-diag -famme' outputs.
Well, it appears that when a media with MII transceiver is used,
the Tx process state becomes 'Processing setup information', like below
(for media 13):
Port selection is 10mpbs-serial, half-duplex.
Transmit started, Receive started, half-duplex.
The Rx process state is 'Waiting for packets'.
The Tx process state is 'Processing setup information'.
The transmit threshold is 72.

I guess it should work with options=3 (100baseTx)

So, for some cases it only transmits, while for others it only
receives... Anyone can help? Anything I could change in the
driver? Anything related to the switch port to which the
notebook is connected (though windows works perfectly :^(
?
Thanks.
