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
