> Subject: [Intel-wired-lan] [PATCH iwl-next v1 1/3] i40e: prepare for
> XDP metadata ops support
>
> Prepare 'struct i40e_xdp_buff' that contains an xdp_buff and a pointer
> to i40e_rx_desc in order to pass the RX descriptor to the XDP kfuncs.
> Also in ZC path, use XSK_CHECK_PRIV_TYPE() to ensure i40e_xdp_buff
> doesn't exceed the offset of cb in xdp_buff_xsk.
>
> No functional changes.
