From df173bda2639ac744ccf596ec1f8f7e66fe4c343 Mon Sep 17 00:00:00 2001 From: stephen hemminger Date: Wed, 23 Feb 2011 13:04:19 +0000 Subject: netem: define NETEM_DIST_MAX Rather than magic constant in code, expose the maximum size of packet distribution table in API. In iproute2, q_netem defines MAX_DIST as 16K already. Signed-off-by: Stephen Hemminger Signed-off-by: David S.
