Members
Header
The NDIS_OBJECT_HEADER structure for the NDIS_RESTART_GENERAL_ATTRIBUTES structure. NDIS sets the Type member of the structure that Header specifies to NDIS_OBJECT_TYPE_RESTART_GENERIC_ATTRIBUTES.
To indicate the version of the NDIS_RESTART_GENERAL_ATTRIBUTES structure, NDIS sets the Revision member to one of the following values:
NDIS_RESTART_GENERAL_ATTRIBUTES_REVISION_2
Added the MaxLookaheadSizeAccessed member for NDIS 6.2.
NDIS sets the Size member to NDIS_SIZEOF_RESTART_GENERAL_ATTRIBUTES_REVISION_2.
NDIS_RESTART_GENERAL_ATTRIBUTES_REVISION_1
Original version for NDIS 6.0 and NDIS 6.1.
NDIS sets the Size member to NDIS_SIZEOF_RESTART_GENERAL_ATTRIBUTES_REVISION_1.
MtuSize
The maximum transfer unit (MTU) size. For more information, see OID_GEN_MAXIMUM_FRAME_SIZE.
MaxXmitLinkSpeed
The maximum transmit link speed of the adapter in bits per second. For more information, see OID_GEN_MAX_LINK_SPEED.
MaxRcvLinkSpeed
The maximum receive link speed of the adapter in bits per second. For more information, see OID_GEN_MAX_LINK_SPEED.
LookaheadSize
The lookahead size for the miniport adapter. For more information, see OID_GEN_CURRENT_LOOKAHEAD.
MacOptions
The medium access control (MAC) options for the miniport adapter. For more information, see OID_GEN_MAC_OPTIONS.
SupportedPacketFilters
The packet filter flags for the miniport adapter.
MaxMulticastListSize
The maximum multicast address list size for the miniport adapter. For more information, see OID_802_3_MAXIMUM_LIST_SIZE.
RecvScaleCapabilities
The receive side scaling (RSS) capabilities of the NIC. If the miniport adapter does not support the RSS feature, NDIS sets RecvScaleCapabilities to a pointer to an NDIS_RECEIVE_SCALE_CAPABILITIES structure that is filled with zeros. For more information about RSS, see OID_GEN_RECEIVE_SCALE_CAPABILITIES.
AccessType
A NET_IF_ACCESS_TYPE NDIS network interface access type.
Flags
Reserved.
ConnectionType
A NET_IF_CONNECTION_TYPE NDIS network interface connection type.
SupportedStatistics
The supported statistics. For more information, see the SupportedStatistics member of the NDIS_MINIPORT_ADAPTER_GENERAL_ATTRIBUTES structure.
DataBackFillSize
The required data backfill size, in bytes, of the driver.
ContextBackFillSize
The required context backfill size, in bytes, of the driver.
SupportedOidList
A list of OIDs that the miniport driver supports. For more information, see OID_GEN_SUPPORTED_LIST.
SupportedOidListLength
The size, in bytes, of the OID list that is specified in the SupportedOidList member.
MaxLookaheadSizeAccessed
A ULONG value for the maximum size, in bytes, of the lookahead size requirement for receive queues. A miniport adapter that supports lookahead in VM queues splits a received packet at an offset equal to or greater than the requested lookahead size and DMAs the lookahead data and the post-lookahead data to separate shared memory segments.
Remarks
NDIS passes an NDIS_RESTART_GENERAL_ATTRIBUTES structure to drivers during restart operations. For example, when NDIS calls a miniport driver's MiniportRestart function, NDIS passes a pointer to an NDIS_RESTART_ATTRIBUTES structure to the miniport driver in the RestartAttributes member of the NDIS_MINIPORT_RESTART_PARAMETERS structure.
If the Oid member in the NDIS_RESTART_ATTRIBUTES structure is OID_GEN_MINIPORT_RESTART_ATTRIBUTES, the Data member of NDIS_RESTART_ATTRIBUTES contains an NDIS_RESTART_GENERAL_ATTRIBUTES structure.
