+ Class to represent relevant data model parameters from TR-196/TR-098.
+ This class is effectively read-only.
+
+ This model specifically targets Qualcomm-based BaiCells units running
+ QAFA firmware.
+
+ These models have these idiosyncrasies (on account of running TR098):
+
+ - Parameter content root is different (InternetGatewayDevice)
+ - GetParameter queries with a wildcard e.g. InternetGatewayDevice. do
+ not respond with the full tree (we have to query all parameters)
+ - MME status is not exposed - we assume the MME is connected if
+ the eNodeB is transmitting (OpState=true)
+ - Parameters such as band capability/duplex config
+ are rooted under `boardconf.` and not the device config root
+ - Parameters like Admin state, CellReservedForOperatorUse,
+ Duplex mode, DL bandwidth and Band capability have different
+ formats from Intel-based Baicells units, necessitating,
+ formatting before configuration and transforming values
+ read from eNodeB state.
+ - Num PLMNs is not reported by these units
