Wei Fang 25eb3058eb net: fec: add AF_XDP zero-copy support ... This patch adds AF_XDP zero-copy support for both TX and RX on the FEC driver. It introduces new functions for XSK buffer allocation, RX/TX queue processing in zero-copy mode, and XSK pool setup/teardown. For RX, fec_alloc_rxq_buffers_zc() is added to allocate RX buffers from XSK pool. And fec_enet_rx_queue_xsk() is used to process the frames from the RX queue which is bound to the AF_XDP socket. Similar to the copy mode, the zero-copy mode also supports XDP_TX, XDP_PASS, XDP_DROP and XDP_REDIRECT actions. In addition, fec_enet_xsk_tx_xmit() is similar to fec_enet_xdp_tx_xmit() and is used to handle XDP_TX action in zero-copy mode. For TX, there are two cases, one is the frames from the AF_XDP socket, so fec_enet_xsk_xmit() is added to directly transmit the frames from the socket and the buffer type is marked as FEC_TXBUF_T_XSK_XMIT. The other one is the frames from the RX queue (XDP_TX action), the buffer type is marked as FEC_TXBUF_T_XSK_TX. Therefore, fec_enet_tx_queue() could correctly clean the TX queue base on the buffer type. Also, some tests have been done on the i.MX93-EVK board with the xdpsock tool, the following are the results. Env: i.MX93 connects to a packet generator, the link speed is 1Gbps, and flow-control is off. The RX packet size is 64 bytes including FCS. Only one RX queue (CPU) is used to receive frames. 1.
