Re: DPAA Ethernet traffice troubles with Linux kernel

Hello,

I have tried to figure out why there is a problem with the buffer space but unfortunately without any success. Any ideas? Could you please watch Skateman's video? [1]

Thanks,
Christian

For those interested... i have recorded a video of my X5000 DPAA Ethernet, and the weird problems..
In this Video i am also transfering hundereds of megabytes from my NAS to the X5000.
You will also see pings die... mostly after the 12th packet and giving the no buffer space error..
Hopefully someone might have a clue about what is happening.

    Sorry,

    I've provided the wrong link towards the patch (v1 instead of v3),
    here's the correct one:
