[vortex] Problems with 3com cards using 3c59x module

[Rikard Boström]

Hi,

I have a somewhat strange problem. I'm connected to my ADSL modem
using the ethernet technology.

When I use a 3com NIC that uses the 3c59x module, ifconfig reports
a couple rx errors now and then, shown below:

eth0 Link encap:Ethernet HWaddr xx:xx:xx:xx:xx:xx
inet addr:xxx.xxx.xxx.xxx Bcast: xxx.xxx.xxx.xxx Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:155278 errors:51 dropped:0 overruns:0 frame:102
TX packets:94897 errors:0 dropped:0 overruns:0 carrier:15
collisions:208 txqueuelen:100
RX bytes:192605438 (183.6 Mb) TX bytes:49456127 (47.1 Mb)
Interrupt:5 Base address:0xa400

If I instead use an Intel NIC with the eepro100 module, there is never any
errors!
But both my 3com cards generates errors... why is that?

The ADSL modem can only use half-duplex, which I think should be the reason
for the collisions, right?
