Hi,
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=9afd85c9e4552b276e2f4cfefd622bdeeffbbf26

This commit introduces a weird behaviour on my dlna server, commit was
bisected.

This commit was merged into 4.2 series, which makes my dlna/upnp services
disappear real soon after starting from discovering from other clients.
Localhost seems not to be affected but every external discovery is broken.
The dlna services run on a bridge device with IPV4. Mythtv and Minidlna both
disappear after some minutes of running.
4.2 with those 3 patches reverted makes it work as it should:

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=fcba67c94abe83e0e69a65737000ccbb16a4fa03
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=9afd85c9e4552b276e2f4cfefd622bdeeffbbf26

Do you need any more information to get this really weird bug fixed?

Thanks in advance.
