[libfabric-users] prevent libfabric from using iBridge/Touchbar interface on a MacBook Pro

For testing and development I’m running several processes locally on my MacBook Pro. If I let libfabric choose the interface the tcp and sockets providers will sometimes choose the iBridge/Touchbar as the interface, which doesn’t work. I realize I can set the interface manually, but is it possible for libfabric to automatically ignore this interface? If that’s not possible, can I tell libfabric *not* to use a particular interface, preferably by specifying the MAC address of the interface to ignore? Thanks.
