Rework mvneta_rx_swbm routine in order to process all rx descriptors before
building the skb or run the xdp program attached to the interface.
Introduce xdp_get_shared_info_from_{buff,frame} utility routines to get the
skb_shared_info pointer from xdp_buff or xdp_frame.
This is a preliminary series to enable multi-buffers and jumbo frames for XDP
according to [1]

Lorenzo Bianconi (6):
  xdp: introduce xdp_get_shared_info_from_{buff,frame} utility routines
  net: mvneta: move skb build after descriptors processing
  net: mvneta: move mvneta_run_xdp after descriptors processing
  net: mvneta: drop all fragments in XDP_DROP
  net: mvneta: get rid of skb in mvneta_rx_queue
  net: mvneta: move rxq->left_size on the stack
