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.
