[The IPsec Task Offload feature is deprecated and should not be used.]
The IPSEC_OFFLOAD_V2_UPDATE_SA structure updates information about security associations (SAs) that a miniport driver previously added to a NIC and a pointer to the next IPSEC_OFFLOAD_V2_UPDATE_SA structure in a linked list.
HeaderThe NDIS_OBJECT_HEADER structure for the IPSEC_OFFLOAD_V2_UPDATE_SA structure. Set the Type member of the structure that Header specifies to NDIS_OBJECT_TYPE_DEFAULT, the Revision member to NDIS_IPSEC_OFFLOAD_V2_UPDATE_SA_REVISION_1, and the Size member to NDIS_SIZEOF_IPSEC_OFFLOAD_V2_UPDATE_SA_REVISION_1.
OffloadHandleAn NDIS handle that identifies the SA. The miniport driver provided this handle in response to an OID set request of OID_TCP_TASK_IPSEC_OFFLOAD_V2_ADD_SA.
OperationThe IPsec operation for which the SA is to be used. The IPSEC_OFFLOAD_V2_OPERATION enumeration defines the supported operations.
SpiA 32 bit security parameters index (SPI) for the SA.
SequenceNumberHighOrderThe high-order bit of an IPsec sequence number. This bit is not included in the IPsec header.
The IPSEC_OFFLOAD_V2_UPDATE_SA structure specifies updates for a SA and a pointer to the next IPSEC_OFFLOAD_V2_UPDATE_SA structure in a linked list. The IPSEC_OFFLOAD_V2_UPDATE_SA structure is used with the OID_TCP_TASK_IPSEC_OFFLOAD_V2_UPDATE_SA OID.
