20 dc ports ... 5x 4port dlink cards.
>Description:
Similar to my submission in kern/19603, I have 20 ethernet ports in one
machine. I the test machine that I used to isolate kern/19603, I never
see this bug ... all but one of it's ports are not connected. It appears
that lots of internet traffic is required to exercise this bug.
This bug also doesn't happen with 16 dc ports. The production machine
that produced the crash dump does not exhibit the crash with 16 ports.

>How-To-Repeat:
I can make test hardware, and possibly even environment available
to anyone chasing this
>Fix:
None, yet.
