qib does not support XRC.  Any time you see a messages like this:

Couldn't Open the XRC Domain 38

from an app on qib hardware, it is expected.  The same is true of most hardware.  I think only mlx4 and mlx5 support XRC, but that might need double checking.

Thanks Doug for the confirmation. From our testing, we did find that only mlx4 and mlx5 support XRC.
