If you have collisions on the output of netstat -i, the interface is
half duplex. Among other things, full-duplex operation MUST disable
collision detection. 

Typical duplex mis-match indicator is that one side of the connection
has zero collisions but shows framing or other data errors and the
other end shows many collisions and other errors; esp. late
collisions.
