It also allows to monitor any vlan changes (add/del/option change). The rtm vlan dumps have an extensible format which allows us to add new options and attributes easily, and also to request the kernel to filter on different vlan information when dumping. The new kernel dump code tries to use compressed vlan format as much as possible (it includes netlink attributes for vlan start and end) to reduce the number of generated messages and netlink traffic. The iproute2 support is activated by using the "-d" flag when showing vlan information, that will cause it to use the new rtm dump call and get all the detailed information, if "-s" is also specified it will dump per-vlan statistics as well. Obviously in that case the vlans cannot be compressed. To change per-vlan options (currently only STP state is supported) a new vlan command is added - "set". It can be used to set options of bridge or port vlans and vlan ranges can be used, all of the new vlan option code uses extack to show more understandable errors. The set adds the first supported per-vlan option - STP state. Man pages and usage information are updated accordingly. Example: $ bridge -d vlan show port vlan-id ens13 1 PVID Egress Untagged state forwarding bridge 1 PVID Egress Untagged state forwarding $ bridge vlan set vid 1 dev ens13 state blocking $ bridge -d vlan show port vlan-id ens13 1 PVID Egress Untagged state blocking bridge 1 PVID Egress Untagged state forwarding ==================== Signed-off-by: David Ahern --- 75a35d50a3b003cf4df2f64635b8912ce83dba9c
