also properly delete location data when a user disables
the location option after re-entering config-mode.

This adds a warning that entprise switches with an IGMP/MLD snooping
feature are not supported yet with IGMP/MLD filtering enabled.

For this to work, firstly the Linux bridge on the Gluon node needs to
support Multicast Router Discovery (RFC4286). But this feature was only
added to the Linux kernel recently, in 5.1.

Secondly, a Gluon node would need to periodically send "Multicast Router
Advertisment" (RFC4286) messages, to "announce" the multicast router
port setting on bridge port bat0.

Thirdly, the IGMP/MLD snooping switches would need to implement
RFC4286.

This reverts commit 9b1eb40f.

With the batman-adv v2019.2 upgrade reverted (c1a77339), the batman-adv
multicast-to-multi-unicast feature is not available yet. Without that it is
going to be very unlikely of the batman-adv multicast optimizations to
take effect. E.g. some outdated nodes would disable it.

To avoid confusion and diversion with a few communities having it enabled
and most implicitly deactivated, just deactivate it for all for now
until batman-adv is updated to v2019.2 or greater again.

The kernel partition on these devices is too small for the
OpenWrt 19.07 kernel. It is also located after the rootfs, so
we cannot grow it further.

Therefore mark these devices as deprecated now.

Fixes #1821

reduce size by removing dispensable packages,
to fix builds of this target in most cases.

gluon-mesh-babel conigures babeld and thus the mesh. This mesh is only usable
with routes to the clients which are discovered by l3roamd.

* add check_site.lua to validate required field from site
* make use of node_client_prefix6 if defined in site

This adds documentation for the gluon-mesh-batman-adv package and
elaborates on its build and configuration options, as well as
the implemented multicast architecture.

mac_to_ip() calculates an ipv6 address from a mac address according to
RFC 4291. For wireguard we have to use specially crafted addresses that
must be unique. This allows calculating such unique mac-based addresses
by allowing to optionally specifying the bytes to be inserted into the
address.

The new routing_algo site.conf value BATMAN_IV_LEGACY is introduced. With
these changes, the routing_algo setting becomes mandatory.

We cannot add the same file (here: /lib/gluon/mesh-batman-adv/compat) to
two, installed packages. Therefore, instead of determining the compat
version number from this file, infer it from the batman-adv release
version number instead.

Instead of unconditionally loading this module on boot the gluon_bat0
netifd protocol script will later take care of loading either the
batman-adv or batman-adv-legacy module, depending on the configured routing
algorithm in UCI.

This displays the branch, repo and commitID that was attempted to update to but
failed. Users then can compare this output to the configuration they meant to
activate in modules and hopefully better find their typos.

Fixes #1775

This is a fix for the broken ingress traffic-shaping in gluon v2018.2.2
and possibly earlier.

For ingress traffic shaping the kernel option NET_ACT_POLICE is needed.
Before this patch there was no dependency to this. Neither in
gluon_core, gluon-mesh-vpn-core nor in the package.

This patch adds this dependency.

Devices featuring ath10k radios should at least 128 MB of memory
as their driver is quite memory hungry.

Devices with a configuration (1x ath10k, 64M memory) like this have
often been seen as running out of memory.
