I think I got my answer from the 3Com website.
Question: Can the EtherLink III family of adapters operate in promiscuous
mode?
Answer: All EtherLink III family adapters are certified for promiscuous
mode. However, the parallel task feature of these adapters does not support
the promiscuous mode since it drops the bad packets before it gets to the
CPU.

Subject: 3C509B Card
Date: Sat, 23 Aug 1997 08:56:59 -0700
From: Cy Schubert <cy@cwsys>
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

lp0* 1500 <Link> 0 0 0 0 0

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
ed0 1500 <Link> 00.00.c0.d9.b1.4a 444764 0 453362 0 12447

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.
