trafgen: take advantage of PACKET_QDISC_BYPASS sock option
Since Linux 3.14, the kernel supports a socket option PACKET_QDISC_BYPASS, which trafgen enables by default. That allow us to bypass the kernels normal qdisc (traffic control) layer. An option -q, --qdisc-path is added to allow enabling the qdisc path explicity, useful for testing purposes. This will be avail in kernels >= 3.14 via commit d346a3fae3 (packet: introduce PACKET_QDISC_BYPASS socket option). Signed-off-by: Jesper Dangaard Brouer <brouer@redhat.com>
