* 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.
