It does bind. Look in linux/net/packet/af_packet.c (I think that's right).
When you bind it to an interface index & protocol, that is coppied into the socket
struct
in the kernel, then when you use sendto, w/out specifying a 'to' sockaddr_ll, then
the kernel will use the previously bound values...
At least that was how I interpretted it..and it seemed to be working for me.
