[PATCH 7/9] netem: dump distribution table
From: Stephen Hemminger <hidden>
Date: 2010-08-06 19:38:05
The existing netem API is not symmetric; the current distribution table is not added to dump output. Since distribution table is could be large, only add it if there space available (for compatiablity with older applications). Signed-off-by: Stephen Hemminger <redacted>
