I feel EAL is not the right place for CMAN definitions.
After a discussion with Jerin, I understand we could use
the same definitions in other API classes, not only ethdev.
However I think this .h file should be better hosted in
lib/ethdev/ with its own namespace rte_cman.
Then other libs could include this rte_cman.h
without having a strong dependency on ethdev.
Deal?
