Alexander Lobakin 084ceda7de libeth: xdp: add .ndo_xdp_xmit() helpers ... Add helpers for implementing .ndo_xdp_xmit(). Same as for XDP_TX, accumulate up to 16 DMA-mapped frames on the stack, then flush. If DMA mapping is failed for some reason, don't try mapping further frames, but still flush what was already prepared. DMA address of a head frame is stored in its headroom, assuming it has enough of it for an 8 (or 4) byte value. In addition to @prep and @xmit driver callbacks in XDP_TX, xmit also needs @finalize to kick the XDPSQ after filling.
