[PATCH v1 0/5] prefix lcore role enum values

[Huisong Li]

Add the RTE_LCORE_ prefix to the lcore role enum values in rte_lcore_role_t
to follow DPDK naming conventions.

- ROLE_RTE      -> RTE_LCORE_ROLE_RTE
- ROLE_OFF      -> RTE_LCORE_ROLE_OFF
- ROLE_SERVICE  -> RTE_LCORE_ROLE_SERVICE
- ROLE_NON_EAL  -> RTE_LCORE_ROLE_NON_EAL

Old names are kept as macros aliasing to the new names to preserve
backward compatibility.

Squashed and applied, thanks.

I have a doubt about RTE_LCORE_ROLE_RTE: could we find a better name?

Also we should probably add some comments to explain each role.

Yes, it made more sense when lcores were either used by DPDK or not.
Note that it's used by both workers and the main lcore.

+1

BTW, I thought the Non-EAL role was for registered control plane threads. But then I looked into Grout.
Grout uses the Non-EAL role for its dataplane threads. And the RTE role for its main thread, which is handling the control plane (which I suppose is not unusual).

Lcore roles and CPU core isolation is very flexible in DPDK. Maybe too flexible.

The problem with this patch it causes build failures now with abi diff.
