Subject: [dpdk-dev] [PATCH] service: add corelist to EAL arguments

This commit allows the -S (captial 's') to be used to indicate
a corelist for Services. This is a "nice to have" patch, and does
not modify any of the service core functionality.

Do we need a new parsing function here?
Can't we reuse at least part of '-l' parsing code?
Konstantin

Yep we should - in this instance (post-RC2..) I don't want to rock-the-boat and change

any existing EAL functionality.

During review of eventdev-sample-app and service-cores, Jerin had noted that we are

duplicating various functions for parsing strings, and

really we should cleanup into a single function to call from all of them. That should be

scheduled as post 17.08 rework.

Sound ok to me then.

Cool. I should note; good point, absolutely agree, and thanks for review :)
