That's sort of my issue as well. We have a couple of these cards being 
used for telco connections in colos.

One seemed to work fine to a certain carrier, once we got them to enable 
autonegotiation on their end.

Now we're trying to bring up another link, with a different carrier, and 
running into all sorts of issues.

Having autonegotiation be my only option gives me very few tools to work 
with. I was hoping that if the 1-port SFP PIM allowed autonegotiation to 
be disabled I could at least use that for troubleshooting the issue.

The 6-port cards allow you to configure gigether-options 
no-auto-negotiation, they just log that they don't actually support it.
