[dpdk-dev,v2] app/testpmd: change log level at run time
Checks
Commit Message
Introduced a run time command to change the
log level for a given log type. Added the
necessary documentation.
V2: Changed the position of the command in
the documentation since generic commands
are placed at the beginning.
