# \[PATCH net\] net: bridge: vlan: fix inverted default vlan notification - From: Nikolay Aleksandrov \ - Date: 2026-08-14 14:16:58 - List: netdev - Page: https://ratatoskr.run/netdev/2026/08/17413065 - Thread: https://ratatoskr.run/netdev/2026/08/17413065/t.md ```text A notification should be emitted only when the vlan delete was successful and not otherwise. The proper check is if br/nbp_vlan_delete returned 0.
