Issue description

none or auto values are no more allowed to IPv4 and IPv6 settings unlike it is described in the network documentation.

Steps to reproduce

1. lxc init images:alpine/3.10 alpine
2. lxc network attach lxdbr0 alpine eth0
3. lxc config device set alpine eth0 ipv4.address auto
   • Expected result: From lxc config show alpine

     devices:
     eth0:
     ipv4.address: auto
     nictype: bridged
     parent: lxdbr0
     type: nic

   • Current result: The following error message:
     Error: Invalid devices: Invalid value for device option ipv4.address: Not an IPv4 address: auto

Information to attach

• [ ] Any relevant kernel output (dmesg)
• [ ] Container log (lxc info NAME --show-log)
• [ ] Container configuration (lxc config show NAME --expanded)
• [ ] Main daemon log (at /var/log/lxd/lxd.log or /var/snap/lxd/common/lxd/logs/lxd.log)
• [ ] Output of the client with --debug
• [ ] Output of the daemon with --debug (alternatively output of lxc monitor while reproducing the issue)

[stgraber]

You're getting confused between the valid values for LXD networks (lxc network edit lxdbr0) and container devices (lxc config edit alpine).

The none/auto values are only valid for networks, not for network interfaces. For network interfaces, they must either be set to an address in the network's subnet or not be set at all.

My bad, thanks for the clarification.
