I am surprised that you didn't use ng_eiface(4) for the same purpose.
If you attach ng_hole(4) to the ng_eiface, then you'll get the same
functionality as edsc(4). But if you attach with ngctl(8) to the
interface via ng_socket(4) you will get a hex dump of the frames
sent to the interface.
AFAIK, the edsc(4)'s functionality is already present in the system.
Totus tuus, Glebius.
