Subject: [PATCH net-next 0/6] mvneta: introduce XDP multi-buffer support

Finalize XDP multi-buffer support for mvneta driver introducing the capability
to map non-linear buffers on tx side.
Introduce multi-buffer bit (mb) in xdp_frame/xdp_buffer to specify if
shared_info area has been properly initialized.
Initialize multi-buffer bit (mb) to 0 in all XDP-capable drivers.
Add multi-buff support to xdp_return_{buff/frame} utility routines.

Changes since RFC:
- squash multi-buffer bit initialization in a single patch
- add mvneta non-linear XDP buff support for tx side

Lorenzo Bianconi (6):
  xdp: introduce mb in xdp_buff/xdp_frame
  xdp: initialize xdp_buff mb bit to 0 in all XDP drivers
  net: mvneta: update mb bit before passing the xdp buffer to eBPF layer
  xdp: add multi-buff support to xdp_return_{buff/frame}
  net: mvneta: add multi buffer support to XDP_TX
  net: mvneta: enable jumbo frames for XDP
