68e2617acf Merge branch 'mlxsw-Remove-RTNL-from-route-insertion-path'
Ido Schimmel says:

====================
mlxsw: Remove RTNL from route insertion path

This patch set removes RTNL from the route insertion path in mlxsw in
order to reduce the control plane latency: the time it takes to push
routes from user space to the kernel and mlxsw.

Up until now mlxsw did not have a lock to protect its shared router data
structures and instead relied on RTNL. While this was simple and worked,
it resulted in large control plane latencies as RTNL was heavily
contended - by both the task receiving the netlink messages from user
space and the mlxsw workqueue that programs the routes to the device.

By removing RTNL and introducing a new router mutex, this patch set
reduces the control plane latency by ~80%. A single mutex is added as
inside mlxsw there is not a lot of concurrency. In addition, a more
fine-grained locking scheme is much more error-prone.

Patches #1-#6 are preparations. They add needed locking in NVE and
multicast routing code instead of relying on RTNL
Patch #7 introduces the new mutex
Patches #8-#12 gradually take the lock in various entry points into the
routing code
Patch #13 removes RTNL in places where it is no longer required

9811f7a2c9 mlxsw: spectrum: Remove RTNL where possible
After introducing the router lock in previous patches and making sure it
protects internal router structures, we no longer need to rely on RTNL
to serialize access to these structures.

Remove RTNL from call sites that no longer require it.

Two calls sites that keep taking the lock are
mlxsw_sp_router_fibmr_event_work() and mlxsw_sp_inet6addr_event_work().
The first calls into ACL code that still assumes RTNL is taken. The
second potentially calls into the FID code that also relies on RTNL.
Removing RTNL from these two call sites is the subject of future work.

8e18d85eab mlxsw: spectrum_router: Store NVE decapsulation configuration in router
When a host route is added, the driver checks if the route needs to be
promoted to perform NVE decapsulation based on the current NVE
configuration. If so, the index of the decapsulation entry is retrieved
and associated with the route.

Currently, this information is stored in the NVE module which the router
module consults. Since the information is protected under RTNL and since
route insertion happens with RTNL held, there is no problem to retrieve
the information from the NVE module.

However, this is going to change and route insertion will no longer
happen under RTNL. Instead, a dedicated lock will be introduced for the
router module.

Therefore, store this information in the router module and change the
router module to consult this copy.

The validity of the information is set / cleared whenever an NVE tunnel
is initialized / de-initialized. When this happens the NVE module calls
into the router module to promote / demote the relevant host route.
