Subject: [PATCH iproute2-next 00/17] bridge: vlan: add global multicast options

From: Nikolay Aleksandrov <nikolay@...dia.com>

Hi all,
This set adds support for vlan multicast options. The feature is
globally controlled by a new bridge option called mcast_vlan_snooping
which is added by patch 01. Then patches 2 and 3 add support for dumping
global vlan options and filtering on vlan id. Patch 04 adds support for
setting global vlan options and then patches 05-16 add all the new
global vlan options, finally patch 17 adds support for dumping vlan
multicast router ports. These options are identical in meaning, names and
functionality as the bridge-wide ones.

All the new vlan global commands are under the global keyword:
 $ bridge vlan global show [ vid VID dev DEVICE ]
 $ bridge vlan global set vid VID dev DEVICE ...

I've added command examples in each commit message. The patch-set is a
bit bigger but the global options follow the same pattern so I don't see
a point in breaking them. All man page descriptions have been taken from
the same current bridge-wide mcast options. The only additional iproute2
change which is left to do is the per-vlan mcast router control which
I'll send separately. Note to properly use this set you'll need the
updated kernel headers where mcast router was moved from a global option
to per-vlan/per-device one (changed uapi enum which was in net-next).

Example:
 # enable vlan mcast snooping globally
 $ ip link set dev bridge type bridge mcast_vlan_snooping 1
 # enable mcast querier on vlan 100
 $ bridge vlan global set dev bridge vid 100 mcast_querier 1
 # show vlan 100's global options
 $ bridge -s vlan global show vid 100
port              vlan-id
bridge            100
                    mcast_snooping 1 mcast_querier 1 mcast_igmp_version 2 mcast_mld_version 1 mcast_last_member_count 2 mcast_last_member_interval 100 mcast_startup_query_count 2 mcast_startup_query_interval 3125 mcast_membership_interval 26000 mcast_querier_interval 25500 mcast_query_interval 12500 mcast_query_response_interval 1000

A following kernel patch-set will add selftests which use these commands.

Thanks,
 Nik
