Hi Dave, there's a community contributed version of Cake for EdgeRouter
devices that I've been using for years on production ER-X's:

https://community.ui.com/questions/Cake-compiled-for-the-EdgeRouter-devices/fc1ff27c-f321-4344-8737-fcc755cae8a2

I don't think that works for UniFi/USG devices, however, and one should
note the disclaimer and be careful when installing it. Also, it must be
re-installed after every upgrade.

Cheers,
Pete
