Supply the following if possible:
- Device problem occurs on

ZBT WG3526

- Software versions of OpenWrt/LEDE release, packages, etc.

19.07.05

- Steps to reproduce

Overall:

If I select the LAN1 on a wg3526 from off to untagged, luci wants to make 2 changes, one of which breaks the configuration:

  it renames the network.lan.ifname from eth0.1 to eth0

  it changes the switch port configuration (that one was expected)

Removing network.lan.ifname=eth0.1 and replacing it by network.lan.ifname=eth0 breaks networking. Rollback properly works.

After some other changes / manually fixing it, I have the following board.json:
