While looking at the estimator code, I noticed an incorrect interval number printed in raw for the handles. This patch fixes the formatting. Before patch: root@bytecenter.fr:~# tc -r filter add dev eth0 ingress estimator 250ms 999ms matchall action police avrate 12mbit conform-exceed drop [estimator i=4294967294 e=2] After patch: root@bytecenter.fr:~# tc -r filter add dev eth0 ingress estimator 250ms 999ms matchall action police avrate 12mbit conform-exceed drop [estimator i=-2 e=2] Signed-off-by: Jamie Gloudon <jamie.gloudon@gmx.fr> Signed-off-by: Stephen Hemminger <stephen@networkplumber.org>
