I received some comments from Moshe Lazer about the first patch in this series that I should fix. Mainly, the ibv_query_device_ex() verb as it was defined by the patch doesn't receive an extensible input struct (only an output struct), and doesn't receive the length of the output struct. I'll fix these comments and send a v1.
