Linus Lüssing b0f377de30 kernel: bridge: Implement MLD Querier wake-up calls / Android bug workaround 
Implement a configurable MLD Querier wake-up calls "feature" which
works around a widely spread Android bug in connection with IGMP/MLD
snooping.

Currently there are mobile devices (e.g. Android) which are not able
to receive and respond to MLD Queries reliably because the Wifi driver
filters a lot of ICMPv6 when the device is asleep - including
MLD. This in turn breaks IPv6 communication when MLD Snooping is
enabled. However there is one ICMPv6 type which is allowed to pass and
which can be used to wake up the mobile device: ICMPv6 Echo Requests.

If this bridge is the selected MLD Querier then setting
"multicast_wakeupcall" to a number n greater than 0 will send n
ICMPv6 Echo Requests to each host behind this port to wake
them up with each MLD Query. Upon receiving a matching ICMPv6 Echo
Reply an MLD Query with a unicast ethernet destination will be sent
to the specific host(s).

README.md

Documentation (incomplete at this time, contribute if you can!) may be found at https://gluon.readthedocs.io/.

If you're new to Gluon and ready to get your feet wet, have a look at the Getting Started Guide.

Gluon's developers frequent an IRC chatroom at #gluon on hackint. There is also a webchat that allows for access from within your browser.

Issues & Feature requests

Before opening an issue, make sure to check whether any existing issues (open or closed) match. If you're suggesting a new feature, drop by on IRC or our mailinglist to discuss it first.

We maintain a Roadmap for the future development of Gluon.

Use a release!

Please refrain from using the master branch for anything else but development purposes! Use the most recent release instead. You can list all releases by running git tag and switch to one by running git checkout v2020.2.1 && make update.

If you're using the autoupdater, do not autoupdate nodes with anything but releases. If you upgrade using random master commits the nodes will break eventually.
