Description Petr Horáček 2023-03-22 10:43:20 UTC 
Description of problem:
The underlying OS assigns the default VLAN 1 to a newly created bridge and every port attached to it. That can be an unexpected issue when attaching veth pairs to a bridge, marking then with a VLAN tag 100, but then seeing traffic from both VLAN 1 and 100 on the other end of the veth. Providing a way to set bridge.vlan-default-pvid on the bridge would allow administrators to disable this default behavior or set a different ID.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Create a bridge using nmstate, setting bridge.vlan-default-pvid to None
2. Attach a veth to it

Actual results:
This attribute does not exist

Expected results:
This should be supported and lead into no VLAN assigned to the veth port
