The first patches just prepare the things such that it would be easier to add XDP_TX and XDP_REDIRECT actions. Like adding XDP_PACKET_HEADROOM, introduce helper functions, use the correct dma_dir for the page pool The last 2 patches introduce the XDP actions XDP_TX and XDP_REDIRECT. v2->v3: - make sure to update rxq memory model - update the page pool direction if there is any xdp program - in case of action XDP_TX give back to reuse the page - in case of action XDP_REDIRECT, remap the frame and make sure to unmap it when is transmitted. v1->v2: - use skb_reserve of using skb_put and skb_pull - make sure that data_len doesn't include XDP_PACKET_HEADROOM Horatiu Vultur (7): net: lan966x: Add XDP_PACKET_HEADROOM net: lan966x: Introduce helper functions net: lan966x: Add len field to lan966x_tx_dcb_buf net: lan966x: Update rxq memory model net: lan966x: Update dma_dir of page_pool_params net: lan966x: Add support for XDP_TX net: lan966x: Add support for XDP_REDIRECT .../ethernet/microchip/lan966x/lan966x_fdma.c | 266 +++++++++++++++--- .../ethernet/microchip/lan966x/lan966x_main.c | 5 +- .../ethernet/microchip/lan966x/lan966x_main.h | 19 ++ .../ethernet/microchip/lan966x/lan966x_xdp.c | 70 ++++- 4 files changed, 312 insertions(+), 48 deletions(-)
