thank you for your information..I have implemented exactly the same but in
the receiver side it is not received..so can u please tell me the flow at
transmitter side just at ethernet layer...
I am giving here the functional flow after that can you please tell me....
ip_build_xmit( ) --> output_maybe_reroute( )--> ip_finish_output2( )-->
dev_queue_xmit( ) --> qdisc_run( )--> qdisc_restart --> [
dev->hard_start_xmit( )]
after this above function pointer I am not able to proceed further as it is
in ethernet layer..can you please add the flow to it up to the receiveing
side IP layer...????
waiting for youe response..

I assume that you have a way to get packets from IP layer, i.e. you have
a driver which removes all headers and replaces them with a compressed
RTP header.
You could define a new packet type in if_ether.h and using
dev_add_pack(), define a cRTP_rcv() function for this packet type.
In the rcv() function you could replace the compressed header with the
normal headers again.

Yes. it will work.

change the skb->protocol and eth_proto fields to the new packet type
you have defined.
HTH.
