Sanity checks
downstream interfaces with a vlan need the matching upstream interface with vlan
an ssid with enterprise encryption needs a radius server
f you have not defined as many radios as a device has, we will warn you
If you defined 2 radios bur your config does not use both radios in the interfaces for example.
If you keys/certs do not match, we will fail the configuration.
We will also report things that are entered but not in the schema.
