gif0 was created with 'ifconfig gif0 create', I just forgot to copy

I get the "Operation not permitted" error only when I haven't
enough privileges:

fk@TP51 ~ $ifconfig bridge0 addm gif0
ifconfig: BRDGADD gif0: Operation not permitted

Does your user bob have root privileges and did you try
it as root?
