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.

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 Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll lp0* 1500 <Link> 0 0 0 0 0 ep0 1500 <Link> 00.60.97.d3.32.3e 452413 411 444431 1 0 ep0 1500 cw-subnet/24 cwsys 452413 411 444431 1 0 sl0* 552 <Link> 0 0 0 0 0 ppp0 1500 <Link> 2969 1 3176 0 0 ppp0 1500 bcsc-net2 cschuber.net.go 2969 1 3176 0 0 lo0 16384 <Link> 30126 0 30126 0 0 lo0 16384 localnet localhost 30126 0 30126 0 0 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 ed0 1500 <Link> 00.00.c0.d9.b1.4a 444764 0 453362 0 12447 ed0 1500 cwnet.cwent.c cwtest 444764 0 453362 0 12447 lp0* 1500 <Link> 0 0 0 0 0 lo0 16384 <Link> 7933 0 7933 0 0 lo0 16384 your-net localhost 7933 0 7933 0 0 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.
