Network drivers need to use reverse christmas tree. I spotted a number
of functions getting this wrong. Please review the whole driver.

+			  sizeof(req), sizeof(resp));
+
+	err = gdma_send_request(gc, sizeof(req), &req, sizeof(resp), &resp);

+		pr_err("%s, line %d: err=%d, err=0x%x\n", __func__, __LINE__,
+		       err, resp.hdr.status);

I expect checkpatch complained about this. Don't use pr_err(), use
dev_err(pdev->dev, ...  of netdev_err(ndev, ... You should always have
access to dev or ndev, so please change all pr_ calls.

+module_param(num_queues, uint, 0444);

No module parameters please.
