       * reg  : bnxt_alloc_rx_rings
       * unreg: bnxt_free_rx_rings
      
      This driver should be updated to re-register when changing
      allocation mode of RX rings.
      
      Tested on actual hardware.

      xdp/qede: setup xdp_rxq_info and intro xdp_rxq_info_is_reg · c0124f32
      Jesper Dangaard Brouer 提交于
      The driver code qede_free_fp_array() depend on kfree() can be called
      with a NULL pointer. This stems from the qede_alloc_fp_array()
      function which either (kz)alloc memory for fp->txq or fp->rxq.
      This also simplifies error handling code in case of memory allocation
      failures, but xdp_rxq_info_unreg need to know the difference.
      
      Introduce xdp_rxq_info_is_reg() to handle if a memory allocation fails
      and detect this is the failure path by seeing that xdp_rxq_info was
      not registred yet, which first happens after successful alloaction in
      qede_init_fp().
      
      Driver hook points for xdp_rxq_info:
       * reg  : qede_init_fp
       * unreg: qede_free_fp_array
      
      Tested on actual hardware with samples/bpf program.
      
      V2: Driver have no proper error path for failed XDP RX-queue info reg, as
      qede_init_fp() is a void function.

      i40e: setup xdp_rxq_info · 87128824
      Jesper Dangaard Brouer 提交于
      The i40e driver has a special "FDIR" RX-ring (I40E_VSI_FDIR) which is
      a sideband channel for configuring/updating the flow director tables.
      This (i40e_vsi_)type does not invoke XDP-ebpf code.
      
      As suggested by Björn (V2): Instead of marking this I40E_VSI_FDIR RX-ring
      a special case, reverse the logic and only select RX-rings of type
      I40E_VSI_MAIN to register xdp_rxq_info's for.
      
      Driver hook points for xdp_rxq_info:
       * reg  : i40e_setup_rx_descriptors (via i40e_vsi_setup_rx_resources)
       * unreg: i40e_free_rx_resources    (via i40e_vsi_free_rx_resources)
      
      Tested on actual hardware with samples/bpf program.
      
      V2: Fixed bug in i40e_set_ringparam (memset zero) + match on I40E_VSI_MAIN.
      V4: Update patch desc that got out-of-sync with code.

      xdp/mlx5: setup xdp_rxq_info · 0ddf5432
      Jesper Dangaard Brouer 提交于
      The mlx5 driver have a special drop-RQ queue (one per interface) that
      simply drops all incoming traffic. It helps driver keep other HW
      objects (flow steering) alive upon down/up operations.  It is
      temporarily pointed by flow steering objects during the interface
      setup, and when interface is down. It lacks many fields that are set
      in a regular RQ (for example its state is never switched to
      MLX5_RQC_STATE_RDY). (Thanks to Tariq Toukan for explanation).
      
      The XDP RX-queue info for this drop-RQ marked as unused, which
      allow us to use the same takedown/free code path as other RX-queues.
      
      Driver hook points for xdp_rxq_info:
       * reg   : mlx5e_alloc_rq()
       * unused: mlx5e_alloc_drop_rq()
       * unreg : mlx5e_free_rq()
