OID_WW_TAC_BUFFER_EXCEPTION
The OID_WW_TAC_BUFFER_EXCEPTION OID requests the miniport driver to return various NIC-related buffer conditions. Protocols can query for these conditions or can request to receive these conditions if operations occur. Queries receive the most recently recorded buffer conditions.
Return values from this request are limited to the values contained in the WW_TAC_BFR_EXCEPTION enumeration. The following lists the valid values.
DATATAC_BFRX_OK
No known buffer-related errors occurred.DATATAC_BFRX_OVERFLOW
Buffer-overflow error occurred.DATATAC_BFRX_ERROR
An unspecified buffer-related error occurred. The device should possibly be returned for service.
If any bound protocol has enabled indications with OID_WW_GEN_INDICATION_REQUEST, the miniport driver must call NdisMIndicateStatusto notify such protocol(s) that the status of an operation generated a status condition from the preceding list. Note however, to improve system performance, miniport drivers should only generate indications if an operation resulted in a status other then DATATAC_BFRX_OK. The miniport driver can ignore the TriggerValue member that was specified in the OID_WW_GEN_INDICATION_REQUEST.
Sets are irrelevant for this OID.
Note This OID is not available for use beginning with Windows Vista.
