Previously, when an Infiniband device was disconnected, the kernel in some cases reported a problem that the interface was removed. As a consequence, the NetworkManager's internal state of this device became corrupted. This bug has been fixed, and the NetworkManager service works as expected to provide consistent information about the state of the device.
This bug has been copied from bug #1498755 and has been proposed to be backported to 7.4 z-stream (EUS).
This works as it used to work back in 7.3 kernel.
Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
resolution of ERRATA.
