it looks like a special function for Intel xmm modems.
Would't it be better to have a vendor-specific extension in the plugin?

I really wouldn't know how to use it for other modems.
And if there is a simple RF filter in the HW, the whole thing is unneeded.

Confused. What is *header? Is MobileNetworkCode uint16 or string?

So I don't mind this living inside doc, but lets make sure to make it 
clear that this is an intel only feature.

So perhaps doc/intel-lte-coex-api.txt

Hmm, why is this property on the Agent interface?  Are these meant to be 
on the LTECoexistence interface?

Also, given that Coex is already in the interface name, I'd just call 
this BluetoothActive.

Similarly here, WiFiActive

Isn't this the channel 'width'?  So WiFiChannelWidth?
