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

NUM_MDHA_STATIC_UNLOAD_CTX_DESC defines the number of descriptors within the

DPD_MD_SA_ULCTX_GROUP that use this request.

DPD_MD_SA_ULCTX_GROUP (0x4300) defines the group for all descriptors within this request.
