Well, since we don't control the core of OpenBTS, could we make the
transceiver compatible with both ways?
Also setting the Tx/Rx gains is a proper way for Multi-ARFCN version
where ARFCN are actually on the same TRX. So we have to make this
compatible with both ways anyway. E.g. we could introduce a new
command to configure transceiver regarding TRXs.

What is the reason you disabled setting power
attenuation an receive
gain for the second trx? Since both channels in UmTRX are independent,
it should be possible to control tx power and rx gain independently.
In the "SETPOWER" command handler:
if (mPrimary)
mRadioInterface->setPowerAttenuation(dbPwr);
The control interface was setup for OpenBTS, which does not make a
distinction between independent channel gain. So I locked both gain
settings to the primary channel (the one that initializes the device).
For better osmo-bts usage, I split the gain settings in the same way
that we discussed for the tuning setting. Note that this breaks
OpenBTS usage, but that fix should really be in core and not the
transceiver.
