I don't see anything touching this code there. The patch that
introduced this code upstream, 521e575b ("IB/mlx4: Add support for

see anything else that changed that area of the code.

The "!" operator has precedence over the "&" operator so parenthesis are required to properly evaluate the user's loopback requirement.
