The commit log has grammar mistakes. And I think you can simply explain what the patch does like:
This patch adds more err info for Tx/Rx descriptor query command.

And the print should be "Invalid input: queue id = 0, desc id = 9999" because you still don't tell users if it's queue id err or desc id err.
