Extend the current support of XDP in lan966x with the action XDP_TX and XDP_REDIRECT. The first patch introduced a headroom for all the received frames. This is needed when the XDP_TX and XDP_REDIRECT is added. The next 2 patches, just introduced some helper functions that can be reused when is needed to transmit back the frame. The last 2 patches introduce the XDP actions XDP_TX and XDP_REDIRECT. 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 (5): net: lan966x: Add XDP_PACKET_HEADROOM net: lan966x: Introduce helper functions net: lan966x: Add len field to lan966x_tx_dcb_buf net: lan966x: Add support for XDP_TX net: lan966x: Add support for XDP_REDIRECT .../ethernet/microchip/lan966x/lan966x_fdma.c | 177 ++++++++++++++---- .../ethernet/microchip/lan966x/lan966x_main.c | 5 +- .../ethernet/microchip/lan966x/lan966x_main.h | 15 ++ .../ethernet/microchip/lan966x/lan966x_xdp.c | 39 +++- 4 files changed, 195 insertions(+), 41 deletions(-) -- 2.38.0
