i40e: setup xdp_rxq_info
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.
