DOT11_MPDU_MAX_LENGTH_INDICATION (Compact 7)

3/12/2014

This structure is used by a miniport driver when it makes an NDIS_STATUS_DOT11_MPDU_MAX_LENGTH_CHANGED indication after the maximum media access control (MAC) protocol data unit (MPDU) frame size is changed for a PHY on the 802.11 station.

Syntax

typedef struct _DOT11_MPDU_MAX_LENGTH_INDICATION {
  NDIS_OBJECT_HEADER  Header;
  ULONG  uPhyId;
  ULONG  uMPDUMaxLength;
} DOT11_MPDU_MAX_LENGTH_INDICATION, *PDOT11_MPDU_MAX_LENGTH_INDICATION;

Members

• Header
  The type, revision, and size of the DOT11_MPDU_MAX_LENGTH_INDICATION 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	DOT11_MPDU_MAX_LENGTH_INDICATION_REVISION_1
  Size	This member must be set to sizeof(DOT11_MPDU_MAX_LENGTH_INDICATION)

• uPhyId
  The identifier (ID) of the PHY on which the maximum MPDU length was changed. The PHY ID is the index within the list of supported PHYs that are returned by the driver through a query of OID_DOT11_SUPPORTED_PHY_TYPES.

  The uPhyID member is applicable only for miniport drivers that operate in Extensible Station (ExtSTA) mode.

• uMPDUMaxLength
  The new maximum length for MPDU frames that are supported by the PHY that is identified by the uPhyID member.

  The uMPDUMaxLength member is applicable only for miniport drivers that operate in Extensible Station (ExtSTA) mode.
