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

Give a RHEL system with HSR ports
When customer use nmstate to create HSR interface using HSR ports without defining MAC address
Then nmstate create a HSR interface with one HSR port holding different MAC address which causing HSR malfunction.

What is the impact of this issue to you?

HSR interface not been set correctly and lose failover ability.

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

nmstate-2.2.46-1.el9

How reproducible is this bug?:

100%

Steps to reproduce

echo '  - name: hsr0
    type: hsr
    state: up
    copy-mac-from: eth1
    hsr:
      port1: eth1
      port2: eth2
      multicast-spec: 40
      protocol: prp' | sudo nmstatectl apply -

ip link

Expected results

The hsr0, eth1 and eth2 are all holding the same MAC address

Actual results

The hsr0, eth1 and eth2 are all holding the same MAC address

The workaround for this is just use `copy-mac-from` to set MAC address explicitly.
