       "A decent batch of fixes here. I'd say about half are for problems that

      Or Gerlitz authored
      Currently, duplicated rules are rejected only for skip_hw or "none",
      hence allowing users to push duplicates into HW for no reason.
      
      Use the flower tables to protect for that.

      ====================
      bnxt_en: Bug fixes.
      
      The first patch fixes a regression on CoS queue setup, introduced
      recently by the 57500 new chip support patches.  The rest are
      fixes related to ring and resource accounting on the new 57500 chips.

      bnxt_en: Fix _bnxt_get_max_rings() for 57500 chips. · e30fbc33
      Michael Chan authored
      The CP rings are accounted differently on the new 57500 chips.  There
      must be enough CP rings for the sum of RX and TX rings on the new
      chips.  The current logic may be over-estimating the RX and TX rings.
      
      The output parameter max_cp should be the maximum NQs capped by
      MSIX vectors available for networking in the context of 57500 chips.
      The existing code which uses CMPL rings capped by the MSIX vectors
      works most of the time but is not always correct.

      bnxt_en: Fix NQ/CP rings accounting on the new 57500 chips. · c0b8cda0
      Michael Chan authored
      The new 57500 chips have introduced the NQ structure in addition to
      the existing CP rings in all chips.  We need to introduce a new
      bnxt_nq_rings_in_use().  On legacy chips, the 2 functions are the
      same and one will just call the other.  On the new chips, they
      refer to the 2 separate ring structures.  The new function is now
      called to determine the resource (NQ or CP rings) associated with
      MSIX that are in use.
      
      On 57500 chips, the RDMA driver does not use the CP rings so
      we don't need to do the subtraction adjustment.

      bnxt_en: Keep track of reserved IRQs. · 75720e63
      Michael Chan authored
      The new 57500 chips use 1 NQ per MSIX vector, whereas legacy chips use
      1 CP ring per MSIX vector.  To better unify this, add a resv_irqs
      field to struct bnxt_hw_resc.  On legacy chips, we initialize resv_irqs
      with resv_cp_rings.  On new chips, we initialize it with the allocated
      MSIX resources.

      bnxt_en: Fix CNP CoS queue regression. · 804fba4e
      Michael Chan authored
      Recent changes to support the 57500 devices have created this
      regression.  The bnxt_hwrm_queue_qportcfg() call was moved to be
      called earlier before the RDMA support was determined, causing
      the CoS queues configuration to be set before knowing whether RDMA
      was supported or not.  Fix it by moving it to the right place right
      after RDMA support is determined.
