Subject: 3C509B Card

Recently I replaced a faulty SMC Elite 16 card with a 3COM 3C509B card.  It's
been working fine, almost too fine.  Since installing the card I haven't seen
any collisions.  My network consists of a P120 with the 3C509B and a 486DX/33
with an SMC Elite 16 connected via thinnet up through the attic of my house.

Is it possible that the Parallel Tasking feature of the card is handling
collisions itself without reporting them to FreeBSD?  Or, is there a bug in
the FreeBSD driver that it's not recognizing or reporting collisions.  As I
write this the netstat -i on the P120 (3C509B) reports:

cwsys$ netstat -i

cwsys$ 

And the netstat -i on the 486 (SMC Elite 16) reports:

cwsys$ rsh cwtest netstat -i
Name  Mtu   Network       Address            Ipkts Ierrs    Opkts Oerrs  Coll

cwsys$ 

The card is working fine.  It's just puzzling that I see these kind of numbers
from netstat.  When I had an SMC card installed in the P120 it too reported
collisions.
