> Subject: [PATCH v4 1/4] common/iavf: support raw packet in protocol header
>
> The patch extends existing virtchnl_proto_hdrs structure to allow VF to pass a
> pair of buffers as packet data and mask that describe a match pattern of a
> filter rule. Then the kernel PF driver is requested to parse the pair of
> buffer and
> figure out low level hardware metadata (ptype, profile, field vector.. ) to
> program the expected FDIR or RSS rules.
