[dpdk-dev] [PATCH v2 3/3] app/testpmd: qualify profiling statistics on burst size
Viacheslav Ovsiienko

Thu Mar 19 14:50:51 CET 2020
The execution time of rx/tx burst routine depends on the burst size.
It would be meaningful to research this dependency, the patch
provides an extra profiling data per rx/tx burst size.
