This object indicates the level of calibration
supported by the implementation. The semantics
are follows.
'inCapable' - This station can't participate in a
calibration procedure initiated by another station.
'unableToInitiate' - This station can involve in
calibration, but cannot apply reciprocity correction
vector received from the initiator and cannot
initiate calibration.
'ableToInitiate' - This station can initiate
calibration but cannot apply reciprocity correction
vector received from the initiator.
'fullyCapable' - This statin can participate in a
calibration procedure initiated by another station,
can respond to a Sounding PPDU and provide a MIMO
channel measurement report in response to the
receipt of a Sounding PPDU. The station can also
apply reciprocity correction vector received from
the initiator of calibration response.
