No. They work like pids.

[relooking at your original message]
First you pass the wrong address to PF_PACKET sendto() -- it gets a
sockaddr_ll, not a old style spkt address.
It is not clear from your snippet where fromlen comes from, but it is
probably not correctly initialized (it should be sizeof(struct sockaddr_ll)
Also sendto really gets a ``to'' not a ``from'', maybe you should fix
the confusing naming.
