The driver implementation of the XDP_REDIRECT action reuses parts from XDP_TX, most notably the enetc_xdp_tx function which transmits an array of TX software BDs. Only this time, the buffers don't have DMA mappings, we need to create them. When a BPF program reaches the XDP_REDIRECT verdict for a frame, we can employ the same buffer reuse strategy as for the normal processing path and for XDP_PASS: we can flip to the other page half and seed that to the RX ring. Note that scatter/gather support is there, but disabled due to lack of multi-buffer support in XDP (which is added by this series): https://patchwork.kernel.org/project/netdevbpf/cover/cover.1616179034.git.lorenzo@kernel.org/ Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S.
