Hi Marcel and Luiz,

Starting with the 2.1 specification, it is my interpretation that it
is not valid to support EIR but not SSP.  I understand that SSP may be
disabled from BlueZ's point of view, but this doesn't seem to be a
legitimate/qualifiable configuration.  Should we instead fail the
legacy pairing if EIR was received as an invalid condition?

Thanks,
Alain
