Hi Viacheslav,

Trace is already saved when dpdk application terminated, I guess this is
to save the trace before exiting the application, what is the use case
for this, can you please detail in the commit log.

And what happens if this is called multiple times, or what happens on
the application exit, will it overwrite the file or fail?
Again please explain in the commit log.

We have dump_* commands, what do you think to have 'dump_trace' command
for this?
