bnxt_en: Re-structure ring indexing and mapping.
In order to support dedicated or shared completion rings, the ring indexing and mapping are re-structured as below: 1. bp->grp_info[] array index is 1:1 with bp->bnapi[] array index and completion ring index. 2. rx rings 0 to n will be mapped to completion rings 0 to n. 3. If tx and rx rings share completion rings, then tx rings 0 to m will be mapped to completion rings 0 to m. 4. If tx and rx rings use dedicated completion rings, then tx rings 0 to m will be mapped to completion rings n + 1 to n + m. 5. Each tx or rx ring will use the corresponding completion ring index for doorbell mapping and MSIX mapping. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.
