[dpdk-dev] l2fwd does not send packets

[Yerden Zhumabekov]

Hi,

To make l2fwd act like a L2 bridge, I had altered l2fwd_simple_forward()
function:

static void
l2fwd_simple_forward(struct rte_mbuf *m, unsigned portid)
{
    unsigned dst_port;
    dst_port = l2fwd_dst_ports[portid];
    l2fwd_send_packet(m, (uint8_t) dst_port);
}
