check out man 7 raw.  the work like any other socket, except for that 
they can have a socket option set so that only L2 data is constructed 
for you. All the L3 data is left for the user to construct.  
Alternatively check out packet sockets (man 7 packet).  they even let 
you construct the L2 data, I believe.
