In multidomain setups, VXLAN is enabled by default, but can be disabled in
domain configs using the mesh/vxlan option. In single domain setups, the
mesh/vxlan option is mandatory.

The UCI option for legacy mode is removed.

gluon-core, gluon-l3roamd: introduce script gluon-list-mesh-interfaces that lists all currently active mesh interfaces

The script cleaned up an old setting that was removed in 2014.

net.ipv6.conf.br-client.forwarding is moved from gluon-client-bridge to
gluon-mesh-batman-adv, as the setting is not useful with non-bridged
protocols.

Our VXLAN setup was changed to accept VXLAN packets without checksum almost
2 months ago, so we can disable sending the checksums now as well. Slightly
improves performance.

Also disabling TX checksums and not only allowing incoming packets without
checksum will provide another small speedup. As doing so would break wired
meshing with VXLAN-enabled nodes that require non-zero checksums, we will
wait a few days before this step.

[Matthias Schiffer: rebase]

Not useful by itself except for testing; will be used for multi-domain
support.

[Matthias Schiffer: rename script, use for initial configuration]

The new proto will simplify the switch to VXLAN encapsulation.

In addition, transitive and fixed_mtu now default to 0 instead of an empty string.

This new protocol will allow configuring mesh interfaces independently of
the used mesh protocol.

The OpenMesh devices have a sticker with the eth0 mac address on the
bottom. Also all other mac addresses are calculated based on this address.
Therefore, it is better to use this as primary mac address instead of the
WiFi mac address.

Also backport some patches improving QCA956x support.

While ath9k/ath10k devices can supprt VIFs with any combination of MAC addresses, there are also adapters which have a hardware MAC filter which only allows a few bits to differ. This commit changes the addresses of all VIFs to ony differ in the last 3 bits, which is required to support many Ralink/Mediatek based WLAN adapters.

Technically, the new addresses are generated by calculating an MD5 hash of the primary MAC address and using a part of this hash as a prefix for the MAC addresses.

The addresses (BSSIDs) of the AP VIFs are also reused for the LAN and WAN interfaces in mesh-on-LAN/WAN mode to reduce the number of needed addresses, and thus reduce the chance of collisions. This is not a problem as the MAC addresses of the AP VIFs are never used except as BSSID, and thus not seen by routing protocols like batman-adv.

[Matthias Schiffer: rewrote commit message]

Device information can be found at:
http://www.8devices.com/products/carambola-2
https://wiki.openwrt.org/toh/8devices/carambola2

I only did some minimal testing of gluon on the carambola 2 development
board:

 - Config mode works
 - Connects to Wifi Mesh
 - Allows clients to connect

Notably, autoupgrade has not yet been tested.

Change to 010-primary-mac is necessary as the mac address printed
on the sticker is the one of eth0, not the wifi mac.

Avoid commiting configs inbetween to decrease number of flash writes.

Fixes #714.

Adopt the according modifications to the default firewall settings of

This new feature introduces the new uci section 'gluon-core.wireless' with a preserve_channels option:
 * preserve_channels (boolean)

By setting this option to 1 (true) wifi channels will be preserved during upgrades.

This will allow us to use its content from other languages than Lua as
well.

Fixes #534

Fixes #487

gluon-radio-config contained only a single file. The code has been adjusted
to allow creating a Gluon configuration without WLAN support by removing
the wifi24 and wifi5 sections from site.conf.
