Update its implementation to account for both TX and RX data. First reply.header carries total payload size within data_off_sizefield. Make use of reply.header to realloc returned buffer with correct size. Failure of IPC request is permissive - error-payload may be returned, an informative data why GET for given param failed - and thus function should not collapse before entire processing is finished. Caller is responsible for checking returned payload and bytes parameters.
