Set a custom file name for pfring_zc_set_proc_stats

[EaseTheWorld]

Well, this is not an issue, more like suggestion.
When I use zbalance_ipc, I want to show its stats.
But pfring_zc_set_proc_stats() saves stat file 'pid'-none.#### which is not predictable.
I think this is for unique filename but cluster_id itself is not enough for uniqueness?
or user-specified name would be possible as well.
(I thought pfring_zc_set_app_name is for this but it's not. what is app_name for?)

pfring_zc_set_app_name is used to set the application name in the /proc/net/pf_ring/ file.
In essence you want to create /proc/net/pf_ring/stats/ with a custom name set by the application.

Yes. custom name(given as zbalance_ipc args) or cluser_num would be useful.
Until yesterday, I didn't know stat file was there and even zbalance_ipc itself doesn't know the filename either.

this could be an interesting enhancement applicable to pfring_set_application_stats() too
