What were you trying to do that didn't work?

If infiniband is attached to bond, using nmstate deletes them doesn't set IB's mtu back to the default value 4092.

What is the impact of this issue to you?

Please provide the package NVR for which the bug is seen:

nmstate-2.2.35-1.el9.x86_64
NetworkManager-1.48.10-2.el9_5.x86_64

ip link show # check mtu

Expected results

IB mtu is reset to 4092
