tcp - is there any way to get ether/ip headers via gen_tcp? -

is there way not body of incoming message. ether/ip headers of it? i'm using gen_tcp , receive messages active controlling process.

for socket opened via 'of_driver' in such way:

gen_tcp:connect(ipaddr, port,  [binary, {packet, raw}, {active, false}],connect_timeout) 

as far know, can't ethernet or ip headers through gen_tcp. use the procket library open raw socket. (the {packet, raw} option passed gen_tcp doesn't refer "raw" socket; means gen_tcp doesn't try interpret tcp byte stream split packets.)
