What was the driver detection message?

Usually FCS/CRC and alignment error indicated corrupted packets due to bad
cables.

The only outstanding problem report with the DS10 is that sometimes the
21143 chips don't switch into full duplex mode, and you get reported
collisions.  This problem is easy to identify:
   the chip is set to full duplex mode
   the Tx collision count is incrementing
I belive that this is fixed with the current driver, but it's a pretty
obscure bug so I can't be certain.
