	I have been trying to implement a new protocol on top of the 
existing ip layer in SunOS using raw sockets. It appears that data received
from a raw socket are prepended by a twenty-byte header. Does anybody
known the exact format of this header? It seems to contain the source and
destination addresses, protocol family and number, data length and some 
other information.
	Thanks in advance.
