Subject: [PATCH net-next 01/10] bnxt_en: Refactor ring reservation functions
The current functions to reserve hardware rings pass in 6 different ring
or resource types as parameters. Add a structure bnxt_hw_rings to
consolidate all these parameters and pass the structure pointer instead
to these functions. Add 2 related helper functions also. This makes
the code cleaner and makes it easier to add new resources to be
reserved.
