Understood, thanks !
I just read all the Doze thing :-) I also recall something published
by Lorenzo about power saving in IPv6, etc., however, I still fail to
see if there is no GUA, why Android is affected using only IPv4.
Well, it is probably a bug. Just could be a bug in a lot of places -
user, kernel, wifi driver, wifi firmware, even wifi hardware. Some of
those are Google-supplied (but possibly manufacturer modified?) but
others are IHV-supplied IIUC.
The fact that IPv6 pulls in a lot more multicast and thus potential wifi
complexity might be related.
It might be interesting to know whether the issue is a failure of e.g.
WMM, so the notify packets aren't being queued to / reaching the
handset, or whether they're being send over the air, but the handset
isn't waking up. Could possibly determine that with a wireshark aircap
on an affected CPE/handset pair if you know the WPA-PSK.
Does the behaviour change if the device is on charge?
