Subject: [PATCH v2 iproute2-next 0/2] tc: support the netem seed parameter for loss and corruption events

From: François Michel <francois.michel@...ouvain.be>

Linux now features a seed parameter to guide and reproduce
the loss and corruption events. This patch integrates these
results in the tc CLI.

For instance, setting the seed 42424242 on the loopback
with a loss rate of 10% will systematically drop the 5th,
12th and 24th packet when sending 25 packets.

v1 -> v2: Address comments and output the seed value
*after* slot information in netem_print_opt().
