Interface removed from bridge on setting change
Closed, ResolvedPublicBUG


When you have a bridge with two interfaces in my case it was an openvpn layer 2 tunnel and a vif vlan interface (like ethX.10).

Then when we edit the configuration from the parent interface (ethX) like by adding a new vlan (ethX.11) the ethX.10 gets removed from the bridge.
