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(). -- Evgeniy Polyakov - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
