xdp: introduce flags field in xdp_buff/xdp_frame
Introduce flags field in xdp_frame and xdp_buffer data structures
to define additional buffer features. At the moment the only
supported buffer feature is frags bit (XDP_FLAGS_HAS_FRAGS).
frags bit is used to specify if this is a linear buffer
(XDP_FLAGS_HAS_FRAGS not set) or a frags frame (XDP_FLAGS_HAS_FRAGS
set). In the latter case the driver is expected to initialize the
skb_shared_info structure at the end of the first buffer to link together
subsequent buffers belonging to the same frame.
