This may be related:
There is a long as a parameter to ccdbuffer that needs to be a u_long.
Otherwise, you'll get panics (can't remember where).
Basically, bcount needs to be a u_long in all cases.
I haven't gotten around, because of the NetMAX for Linux project, to
comitting things like this to the FreeBSD project.
