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

NUM_HMAC_STATIC_PAD_HASH_DESC defines the number of descriptors within the

DPD_HMAC_SA_PAD_HASH_GROUP that use this request.

DPD_HMAC_SA_PAD_HASH_GROUP (0x4700) defines the group for all descriptors within this request.
