Subject: examples/l3fwd-power: fix busyness number
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=b55d8fec46ce1f2a152f3687abb3222f675ce73e;p=dpdk.git

examples/l3fwd-power: fix busyness number

Current implementation only outputs 3 numbers for busyness, 0, 50 and 100.
Fix this so that the 50% is replaced by a curve, more meaningful.
This can be replaced in each use case by a suitable calculation for
that use case.

Fixes: 609e79841fcf ("examples/l3fwd-power: add telemetry mode")
