Thank you very much for your response.
For now, we do not use IPoIB. If I remember correctly bonding interfaces
over two distinct protocols could be problematic, but I will look into it.
Cheers

For various reasons the network interfaces are mapped to the same IP
range e.g. x.x.x.15y (eno1), x.x.x.17y (ib1), x.x.x.18y (ib2) with x
constant for all ports and server and only "y" changing for
individual server.
Don't do this. The Linux kernel will happily answer ARP requests on
any interface for the IPs it has configured anywhere. That means you
have a constant ARP flapping in your network.
Make the three interfaces bonded and configure all three IPs on the
bonded interface.
