    bnxt_en: Re-structure ring indexing and mapping. · b81a90d3
    Michael Chan authored
    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.
