Hi, Guy,

First of all, thanks so much for your help and detailed explanation! --
I really appreciate it...

Yep. Apologies for being sloppy....

I will certainly file a bug report, and CC you. My understanding is that
this should be filled in most (if not all) of the BSD variants? (because
besides the error message one obtains, it seems that in several flavors
of them, pcap_inject() fails for the same reason).

Thanks!
