* Description:  IKEv2 IPsec SA data definition

*                Class TIkeV2IpsecSAData is the IKEv2 specific version of

*                IPsec SA parameter definition which

*                is used to pass SA information between store IPsec SA

*                information internally by the IKEv2 plugin.
