Currently the only available levels are 0 (silent except for error) and 1 (fully verbose).

~~~~~~~
Set the log level for a log type::
testpmd> set log global|(type) (level)
Where:
* ``type`` is the log name.
* ``level`` is the log level.
For example, to change the global log level::
testpmd> set log global (level)
Regexes can also be used for type. To change log level of user1, user2 and user3::
testpmd> set log user[1-3] (level)
set nbport
