Subject: tc: add a missing space between rate estimator and backlog
X-Git-Tag: v4.20.0~36
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3adcbf3757b8ad7f5cac86985ef6335b7981d725;p=thirdparty%2Fiproute2.git

tc: add a missing space between rate estimator and backlog

When a rate estimator is active, "tc -s qd" displays
something like :

rate 12616bit 11ppsbacklog 0b 0p requeues 2

instead of :

rate 12616bit 11pps backlog 0b 0p requeues 2
