OID_TCP_TASK_IPSEC_DELETE_SA

The OID_TCP_TASK_IPSEC_DELETE_SA OID is set by a transport protocol to request that a miniport driver delete a security association (SA) from its NIC. The SA information is formatted as an OFFLOAD_IPSEC_DELETE structure, which is defined as follows:

typedef struct _OFFLOAD_IPSEC_DELETE_SA {
  ULONG  OffloadHandle;
} OFFLOAD_IPSEC_DELETE_SA, *POFFLOAD_IPSEC_DELETE_SA;

The members of this structure contain the following information:

OffloadHandle

Specifies the handle for the SA to be deleted.

On receiving this request, the miniport driver should delete the specified SA from the NIC and free any system resources allocated for the SA.
