Public bug reported:

static routes rendered for eni configuration are not correct

example:

config:
    - mac_address: aa:12:bc:34:ee:ac
      name: eno3
      subnets:
      - address: fd00::12/64
        dns_nameservers: ['fd00:2::15']
        gateway: fd00::1
        ipv6: true
        routes:
        - netmask: '32'
          network: 'fd00:12::'
          gateway: fd00::2
        type: static
      type: physical
    version: 1

Cloud init renders:

but the post-up/pre-down commands are incorrect (tested, even when
replacing the 32 netmask by ffff:ffff::)
