More Further testing on RBEM56G 

Forum: Xircom PCMCIA Ethernet Adapter Issues
Re: Question RBEM56G asymmetrical transfer speeds (Ron Golan)

I just updated to pcmcia-cs-3.1.14 and this is what I found.

The tulip_cb driver is still broken. Can't ping anything. I copied in the one from 3.1.11 which is the last one that worked for me.

The transfer speeds are still asymmetrical. TX is much faster than RX. TX is about 30 times faster if my crude testing methods can be trusted. Below is some ifconfig output:

eth0      Link encap:Ethernet  HWaddr 00:10:A4:F3:64:17  
          inet addr:192.168.10.8  Bcast:192.168.10.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:20730 errors:5 dropped:0 overruns:0 frame:0
          TX packets:7937 errors:17801 dropped:0 overruns:0 carrier:17801
          collisions:0 txqueuelen:100 
          Interrupt:3 Base address:0x1000 

There seem to be a lot of carrier errors. I am using the Xircom RBEM56G at 100baseT and full duplex. It doesn't seem to make any difference if I use a switch or a cross-over cable.
