OK, will update the commit log. The command "save_trace" is useful in some
dynamic debug scenarios to save the trace without restarting the entire application.

It overwrites.

Sure, will do.

It was initially (in v1) with "dump_trace" command.
And there is the comment by Jerin:
https://inbox.dpdk.org/dev/CALBAE1Of79a_jHnFT3KX--Enhud-h5RzL02TMQBsmoW721ds7A@mail.gmail.com/#t
So, I have changed to "save_trace". I have no strong opinion about command name, any allowing trace save is OK for me.
With best regards,
Slava
