Members
Header
The type, revision, and size of the DOT11_PHY_ATTRIBUTES structure. This member is formatted as an NDIS_OBJECT_HEADER structure.
The miniport driver must set the members of Header to the following values:
Type
This member must be set to NDIS_OBJECT_TYPE_DEFAULT.
Revision
This member must be set to DOT11_PHY_ATTRIBUTES_REVISION_1.
Size
This member must be set to sizeof(DOT11_PHY_ATTRIBUTES).
For more information about these members, see NDIS_OBJECT_HEADER.
PhyType
The type of the PHY as specified by a DOT11_PHY_TYPE enumerator value.
bHardwarePhyState
A Boolean value that specifies the hardware power state of the PHY. If TRUE, the hardware power state is enabled. If FALSE, the hardware power state is disabled.
For more information about the PHY's hardware power state, see OID_DOT11_HARDWARE_PHY_STATE.
bSoftwarePhyState
A Boolean value that specifies the software power state of the PHY. If TRUE, the software power state is enabled. If FALSE, the software power state is disabled.
For more information about the PHY's software power state, see OID_DOT11_NIC_POWER_STATE.
bCFPollable
A Boolean value that, if set to TRUE, indicates that the 802.11 station supports CF-Poll frames. For more information about CF-Poll frames, refer to Clause 9.4 of the IEEE 802.11-2012 standard.
This member is not applicable to the Extensible Access Point (ExtAP) operation mode and is ignored when the NIC is in the ExtAP mode.
uMPDUMaxLength
The maximum length, in bytes, of a media access control (MAC) protocol data unit (MPDU) frame that the PHY can transmit or receive. For more information, see OID_DOT11_MPDU_MAX_LENGTH.
TempType
The PHY's operating temperature range, defined through a DOT11_TEMP_TYPE enumeration value.
DiversitySupport
The PHY's type of antenna diversity, defined through a DOT11_DIVERSITY_SUPPORT enumeration value.
PhySpecificAttributes
PhySpecificAttributes.HRDSSSAttributes
The PHY-specific attributes of a high-rate direct-sequence spread spectrum (HRDSS) PHY type. The miniport driver must use this member only if the PhyType member is set to dot11_phy_type_hrdsss.
PhySpecificAttributes.OFDMAttributes
The PHY-specific attributes of an orthogonal frequency division multiplexing (OFDM) PHY type. The miniport driver must use this member only if the PhyType member is set to dot11_phy_type_ofdm.
PhySpecificAttributes.ERPAttributes
The PHY-specific attributes of an extended-rate PHY (ERP) type. The miniport driver must use this member only if the PhyType member is set to dot11_phy_type_erp.
Remarks
The NDIS_MINIPORT_ADAPTER_NATIVE_802_11_ATTRIBUTES structure contains a member (pExtPhyAttributes) that specifies the address of an array of DOT11_PHY_ATTRIBUTES structures. When the miniport driver calls NdisMSetMiniportAttributes, the driver sets the MiniportAttributes parameter to the address of driver-allocated block of memory which contains an NDIS_MINIPORT_ADAPTER_NATIVE_802_11_ATTRIBUTES structure along with the array of DOT11_PHY_ATTRIBUTES structure.
