From: Wei Fang <wei.fang@nxp.com>
We encountered some issues when testing the ndo_xdp_xmit() interface of the fec driver on i.MX8MP and i.MX93 platforms. These issues are easy to reproduce, and the specific reproduction steps are as follows.
step1: The ethernet port of a board (board A) is connected to the EQOS port of i.MX8MP/i.MX93, and the FEC port of i.MX8MP/i.MX93 is connected to another ethernet port, such as a switch port.
step2: Board A uses the pktgen_sample03_burst_single_flow.sh to generate and send packets to i.MX8MP/i.MX93. The command is shown below. ./pktgen_sample03_burst_single_flow.sh -i eth0 -d 192.168.6.8 -m \ 56:bf:0d:68:b0:9e -s 1500
step3: i.MX8MP/i.MX93 use the xdp_redirect bfp program to redirect the XDP frames from EQOS port to FEC port. The command is shown below. ./xdp_redirect eth1 eth0
After a few moments, the warning or error logs will be printed in the console, for more details, please refer to the commit message of each patch.
Wei Fang (3): net: fec: dynamically set the NETDEV_XDP_ACT_NDO_XMIT feature of XDP net: fec: recycle pages for transmitted XDP frames net: fec: increase the size of tx ring and update thresholds of tx ring
