Bug 1858731

We should document that Infiniband cannot be configured on RHV-4.4 hosts yet.
The workaround is to use RHV-4.3 hosts on RHVM-4.4 for hosts with Infiniband.


+++ This bug was initially created as a clone of Bug #1856279 +++

Description of problem:

Version-Release number of selected component (if applicable):
oVirt 4.4.1.8-1.el8

How reproducible:

Steps to Reproduce:
1. Create Infiniband Bond 
2. Create new network with MTU 65520 (uncheck VM Network)
3. Assign created network to IB bond (Go to Hosts --> Netwrok Interface. Drag to IB Bond, press OK)

Actual results:
Error -  "Error while executing action HostSetupNetworks: Unexpected exception"

Expected results:
New network assigned to IB Bond.
