parentbridge: update vlan dev link state for bridge netdev changes (diff)
Merge branch 'net-support-binding-vlan-dev-link-state-to-vlan-member-bridge-ports'
Mike Manning says: ==================== net: support binding vlan dev link state to vlan member bridge ports For vlan filtering on bridges, the bridge may also have vlan devices as upper devices. For switches, these are used to provide L3 packet processing for ports that are members of a given vlan. While it is correct that the admin state for these vlan devices is either set directly for the device or inherited from the lower device, the link state is also transferred from the lower device. So this is always up if the bridge is in admin up state and there is at least one bridge port that is up, regardless of the vlan that the port is in. The link state of the vlan device may need to track only the state of the subset of ports that are also members of the corresponding vlan, rather than that of all ports. This series provides an optional vlan flag so that the link state of the vlan device is only up if there is at least one bridge port that is up AND is a member of the corresponding vlan. v2: - Address review comments from Nikolay Aleksandrov in patches 3 & 4 and add patch 5 to address bridge link down due to STP v3: - Address review comment from Nikolay Aleksandrov in patch 4 so as to remove unnecessary inline #ifdef ==================== Signed-off-by: David S.
