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 (4): > 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 tx_wake_threshold > net: fec: use netdev_err_once() instead of netdev_err() > > drivers/net/ethernet/freescale/fec.h | 17 ++- > drivers/net/ethernet/freescale/fec_main.c | 166 +++++++++++++++------- > 2 files changed, 127 insertions(+), 56 deletions(-) Thanks, Olek
