      Given a system administrator initiates a VF creation and updates in one Nmstate transaction,

      When the command is applied,

      Then the VFs should be created and modified as specified without requiring separate actions.

      Definition of Done:

      • The implementation meets the acceptance criteria
      • Integration tests are written and pass
      • The code is part of a downstream build attached to an errata

      How reproducible is this bug?:

      100%

      Steps to reproduce

      Find an interface that supports SR-IOV, in here take `eno2` as an example:

      echo "
interfaces:
- name: eno2
  type: ethernet
  state: up
  mtu: 2000
  ethernet:
    sr-iov:
      total-vfs: 2
- name: eno2v0
  state: up
  type: ethernet
  mtu: 5000
  ipv4:
    enabled: true
    dhcp: true
  ipv6:
    enabled: true
    dhcp: true
    autoconf: true
- name: sriov:eno2:1
  state: up
  type: ethernet
  mtu: 6000
  ipv4:
    enabled: true
    dhcp: true
  ipv6:
    enabled: true
    dhcp: true
    autoconf: true
" | nmstatectl apply

      Expected results

      Two VFs are created and have the states as the desired.

      Actual results
