OID_DOT11_DESIRED_PHY_LIST (Compact 7)

When set, the OID_DOT11_DESIRED_PHY_LIST object identifier (OID) requests that the miniport driver set the value of the Extensible Station (ExtSTA) msDot11DesiredPhyList management information base (MIB) object to the specified data.

When queried, OID_DOT11_DESIRED_PHY_LIST requests that the miniport driver return the value of the msDot11DesiredPhyList MIB object.

The msDot11DesiredPhyList MIB object specifies the desired PHY list that the 802.11 station uses when it connects to and operates in a BSS network. Each entry in the msDot11DesiredPhyList MIB object is a PHY identifier (IDs). This entry can be one of the following:

  • An index into the table of supported PHYs as defined by the Native 802.11 Operational msDot11SupportedPhyTypes MIB object. For more information about PHY IDs and the msDot11SupportedPhyTypes MIB object, see OID_DOT11_SUPPORTED_PHY_TYPES.
  • A PHY ID with the value of DOT11_PHY_ID_ANY is the wildcard PHY ID. If the msDot11DesiredPhyList MIB object contains the wildcard PHY ID, the 802.11 station can use any supported PHY to connect to and operate in a BSS network.

The msDot11DesiredPhyList MIB object does not define the PHY IDs that can be used by the 802.11 station for scan operations. The PHY IDs that the 802.11 station uses for scanning are specified when OID_DOT11_SCAN_REQUEST is set.

The data type for OID_DOT11_DESIRED_PHY_LIST is the DOT11_PHY_ID_LIST structure.

When OID_DOT11_DESIRED_PHY_LIST is set, the miniport driver must fail the set request if the members of the DOT11_PHY_ID_LIST structure meet the following conditions:

  • The desired PHY list must always contain at least one entry. If uNumOfEntries is set to zero, the miniport driver must fail the request by returning NDIS_STATUS_INVALID_DATA from its MiniportOidRequest function.
  • A desired PHY list that contains a wildcard PHY ID cannot contain other PHY IDs. When OID_DOT11_DESIRED_PHY_LIST is set, the miniport driver must fail the request by returning NDIS_STATUS_INVALID_DATA from its MiniportOidRequest function if the dot11PhyIds array contains the wildcard PHY ID and uNumOfEntries is greater than one.
  • If the dot11PhyId array contains a PHY ID that is not the wildcard PHY ID and has a value greater than or equal to the number of entries defined by the msDot11SupportedPhyTypes MIB object, the miniport driver must fail the request by returning NDIS_STATUS_INVALID_DATA from its MiniportOidRequest function.
  • If the dot11PhyId array contains a PHY ID that is not supported on the 802.11 station, the miniport driver must fail the request by returning NDIS_STATUS_UNSUPPORTED_MEDIA from its MiniportOidRequest function.
  • If the dot11PhyId array contains a PHY ID that has been disabled on the 802.11 station through a proprietary mechanism implemented by the independent hardware vendor (IHV), the miniport driver must fail the request by returning NDIS_STATUS_UNSUPPORTED_MEDIA from its MiniportOidRequest function.

Note

This condition does not apply to PHYs disabled through a set request of OID_DOT11_NIC_POWER_STATE.

When OID_DOT11_DESIRED_PHY_LIST is queried, the miniport driver must verify that the InformationBuffer member of its MiniportOidRequest function’s OidRequest parameter is large enough to return the desired PHY ID list. For more information about this procedure, see DOT11_PHY_ID_LIST.

The default for the msDot11DesiredPhyList MIB object contains a single entry that contains the members of the DOT11_PHY_ID_LIST structure set, as follows:

  • dot11PhyId[0] is set to DOT11_PHY_ID_ANY
  • uNumEntries is set to one

The miniport driver must set the msDot11DesiredPhyList MIB object to its default value when the following occurs:
