Re: DPAA Ethernet traffice troubles with Linux kernel

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.

That doesn't work really, having users to hit the bug, debug it,

fix

it

and then

find it fixed already in upstream, then specifically request it to

backported to stable.

I don't need this fix to be backported, already got it. Someone

might though.

The "someone else might though" is a big point of asking for it to
added to stable. The other reason is it means one less patch you need
to maintain in your build.

I've sent that patch [1] for net but I guess the timing was wrong and
it was merged to net-next.

I would be interested in bug fixes upstream which fixes:

Did you try upstream? Does it give the same errors?

Hi Dave,

Can you please add the fix [1] to stable?

Thank you,
Madalin

Sorry,

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