[LEDE-DEV] revisited: Nanostation m5 XW ethernet patch gone

[Daniel Golle]

Hi Felix!
Hi everyone!

It looks like Tiziano is right and this patch did get lost somehow.
At least I can't find any work-arounds regarding PHY hangs committed in
neither target/linux/generic/files/* nor target/linux/ar71xx/files/*.

The thread on lede-dev also seems to have stagnated after
http://lists.infradead.org/pipermail/lede-dev/2016-December/004406.html

Felix, you said you had a more clean patch for this in your staging
tree?

I'm asking because I might have just hit that bug once again on
UBNT-NM-XW, ie. uid=004dd043, driver=Atheros AR8216/AR8236/AR8316...

Anyone? I've also had a lot of problems with that bug on XW hardware
and have since simply tried to avoid it (the hardware). Now that also
non-loco NanoStations are only available in their XW-version I'd be
happy to finally have a reliable work-around for that hardware problem.


Cheers


Daniel

Hello everyone
Could this patch http://gerrit.aredn.org/#/c/57 be merged in trunk?
I've just tested it with trunk and it works properly on my nanostation loco
m5 xw , the PHY chip is correctly reset every like 8 hours or so and no
connectivity loss since then

I'm not commenting to the bug report because i' both unable to register and
to comment because trac complains that i'm spamming, my ip address range
is 89.202.181.128 - 89.202.181.143
