      Description of problem:
      On latest RHEL 9.3, with SR-IOV enabled, the VF card is assigned a link-local IPv6 address. This happens on both ARM and x86_64 systems.

      1. ip a
        1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000

      Additional info:
      1. We had a similar issue - https://bugzilla.redhat.com/show_bug.cgi?id=2057263.
      Only this time IPv4 address does not exist. Udev rule is still in place.
      2. Latest RHEL 8.9 does not have this issue.
