 * These primitives are used both to determine the set of capabilities in
 * the DLS provider and also to turn on and off specific capabilities.
 * The response is a DL_CAPABILITY_ACK or DL_ERROR_ACK.
 *
 * DL_CAPABILITY_REQ can either be empty (i.e. dl_sub_length is zero) which
 * is a request for the driver to return all capabilities. Otherwise, the
 * DL_CAPABILITY_REQ contains the capabilities the DLS user wants to use and
 * their settings.
 *
 * DL_CAPABILITY_ACK contains the capabilities that the DLS provider can
 * support modified based on what was listed in the request. If a
 * capability was included in the request then the information returned
 * in the ack might be modified based on the information in the request.
