Commit 1bb4a528c41f ("ethdev: fix max Rx packet length") clarified the expected usage of the max_rx_pktlen and max_mtu values and implemented some extra checks on these values to ensure they are sane. After this, the AF_XDP PMD fails to initialise. The value for max_rx_pktlen which represents the max size of the Ethernet frame was set to ETH_FRAME_LEN (1514) and the max_mtu which represents the size of the payload was set to the max size of the Ethernet frame. This did not make sense, as naturally the maximum frame size should be greater than the payload size.Fix this by setting the max_rx_pktlen equal to the max size of the Ethernet frame as expected, and the max MTU equal to the max_rx_pktlen less the overhead which is set to the size of an Ethernet header plus CRC.

Thanks for the fix. Reviewed-by: Ferruh Yigit <ferruh.yi...@intel.com> Applied to dpdk-next-net/main, thanks.
