Hi,
On my COMX-P4080 board from Emerson , I observe Tx packet loss.When I checked the errors, it is seens as tx_fifo_erros.
How do I resolve this issue?
The case is similar to my P4080DS board where packets are lost but I don't observe it as tx_fifo_erros or anything. I suspect it may not be showing in my P4080DS board. But there also there is a packet loss.
It would be very helpful if anyone could suggest anything?
Thanks,
Sharath Chandra
Hello Sharath Chandra,
Please get more detailed debug information with the following command. (Please adjust the parameter according to your Ethernet port).
$ cat /sys/devices/fsl,dpaa.15/ethernet.16/net/fm1-gb1/statistics/tx_fifo_errors
$ cat /sys/devices/fsl,dpaa.15/ethernet.16/net/fm1-gb1/statistics/tx_dropped
$ cat /sys/kernel/debug/powerpc/fsl_dpa/eth0
In addition, would you please provide your Kernel configuration file and dts file?
Have a great day,
Yiping

Hi Yiping,
The issue was with UDP buffer size, after increasing the buffer size. It got resolved.
Thanks,
