====================
mlxsw: Multicast flood update

Nogah says:

Currently, there are four erroneous flows in MC flood:
1. When MC is disabled it affects only the flood table for unregistered
   MC packets, but packets that match an entry in the MDB are unaffected.
2. When MC is disabled, MC packets are being sent to all the ports in the
   bridge (like BC and link-local MC packets) regardless of the designated
   flag (BR_MCAST_FLAG).
3. When a port is being deleted from a bridge it might remain in the MDB.
4. When MC is enabled packets are flooded to the mrouter ports only if
   they don't match any entry in the MDB, when they should always be
   flooded to them.

What these problems have in common is the discrepancy between how the
hardware handles MDB and mcast flood, and how the driver does it. Each
of these problems needs fixing either in the MDB code, or in mcast flood
code, and some in both.

Patches 1-6 change the way the MDB is handled in the driver to make the
following changes easier.
Patches 7-8 fix problem number 1 by removing the MDB from the HW when MC
is being disabled and restoring it when it is being enabled.
Patches 9-10 fix problem number 2 by offloading the flood table by the
appropriate flag.
Patch 11 fixes problem number 3 by adding MDB flush to the port removal.
Patches 12-14 fix problem number 4 by adding the mrouter ports to every
MDB entry in the HW to mimic the wanted behaviour.

Userland may be confused by the fact we say a link is deleted while
its characteristics are only modified. A first solution would have
been to turn the RTM_DELLINK event in del_nbp() into a RTM_NEWLINK
event. However, maybe some piece of userland is relying on this
RTM_DELLINK to detect when a bridged interface is released. Instead,
we also emit a RTM_NEWLINK event once the interface is
released (without master info).

This is done only when using ioctl(). When using Netlink, such an
event is already automatically emitted in do_setlink().

====================
net: speedup netns create/delete time

When rate of netns creation/deletion is high enough,
we observe softlockups in cleanup_net() caused by huge list
of netns and way too many rcu_barrier() calls.

This patch series does some optimizations in kobject,
and add batching to tunnels so that netns dismantles are
less costly.

IPv6 addrlabels also get a per netns list, and tcp_metrics
also benefit from batch flushing.

This gives me one order of magnitude gain.
