+/* There is a known incompatibility for CK_GCM_PARAMS structure.
+ * PKCS#11 v2.40 standard mechanisms specification specifies
+ * CK_GCM_PARAMS as
+ *     typedef struct CK_GCM_PARAMS {
+ *         CK_BYTE_PTR       pIv;
+ *         CK_ULONG          ulIvLen;
+ *         CK_BYTE_PTR       pAAD;
+ *         CK_ULONG          ulAADLen;
+ *         CK_ULONG          ulTagBits;
+ *     } CK_GCM_PARAMS;
+ * However, the official header file of PKCS#11 v2.40 defines the
+ * CK_GCM_PARAMS with an extra "ulIvBits" field (type CK_ULONG).
+ * NSS uses the spec version while Solaris and SoftHSM2 use the header
+ * version. In order to work with both sides, SunPKCS11 provider defines
+ * the spec version of CK_GCM_PARAMS as CK_GCM_PARAMS_NO_IVBITS (as in this
+ * file) and uses it first before failing over to the header version.
