How will your hardware handle that new protocol?
Anyway, you need to setup skb and call driver's ->hard_start_xmit()
callback under tx lock with check if driver allows to transmit data.
Check net/pktgen.c -> pktgen_xmit() function.
The simplest way to receive a packet is about putting your code into
netif_receive_skb().
