My mistake -- found the location a few minutes ago, and must have
overlooked it previously (possibly due to spelling it ifdetach() instead
of if_detach() :-). Apparently bpf likes to use bpfwhatever, and if likes
to use if_whatever. However, if_ep also appears to require the patch.
I've sent you email relating to your response to the commit message for
the patch, in which I provide further details.
