Thank you very much for the detailed bug report and for the patches!

I confirm this bug, the current code misinterprets the "modulation" (BPSK,
QPSK, 16QAM) for the modulation class defined by section 9.6.1 in IEEE
Std. 802.11-2007. 

I agree that your proposed fix works, the only thing I don't like is the
introduction of the method WifiRemoteStationManager::GetPhy
I would wait until we fix 871, to see if we can come with a modified patch that
does not need this method.

I am also fine with the changes to the tests and the regression traces, of
course to be applied after we have a version of the patch that we agree upon.
