OpenWRT now supports the CISCO Meraki enterprise class routers
MR12, MR16, MR62 and MR66. The fabric firmware demands the yearly
renewal of a support license.

This firmware was successfully tested by @Garunda for the MR62 (and
the MR12 with it for which this is an alias). The initial firmware
pre OpenWRT adoption was prepared and adapted for Gluon by @tcatm.
The confirmation of the functionality of the image for the MR66
(and the aliased MR16 with it) is still pending.

The devices are of strategic interest to the Freifunk community as
they are making a rock-solid impression. However, these come with
fairly hefty annual license. The Freifunk may offer an escape route
for those who had signed up and want to keep their investment into the
similarly expensive hardware. Used evices sell for $60 on eBay/Amazon
in the US. Here in the old world it is all >300 €, still.

Credits go to @Garunda for testing, to @tcatm for finding the
OpenWRT patch prior to its adoption and preparing the initial Gluon
adaptation, to @smoe for the update once that patch had arrived in
OpenWRT, and to @NeoRaider for his review and advice to use
GluonModelAlias for MR62 and MR66 to point to MR12 and MR16,
respectively.
