Dynamic channels are not valid for this request. A channel value of zero is invalid.

NUM_DES_LOADCTX_CRYPT_STATIC_DESC defines the number of descriptors within the

DPD_DES_SA_LDCTX_CRYPT_GROUP that use this request.

DPD_DES_SA_LDCTX_CRYPT_GROUP (0x2100) defines the group for all descriptors within this request.
