L3 HW stats are implemented in mlxsw as RIF counters, and therefore the code resides in spectrum_router. Exclude the offload xstats events from the mlxsw_sp_netdevice_event_is_router() predicate, and instead recreate the glue code in the router module. Previously, the order of dispatch was that for events on tunnels, a dedicated handler was called, which however did not handle HW stats events. But there is nothing special about tunnel devices as far as HW stats: there is a RIF associated with the tunnel netdevice, and that RIF is where the counter should be installed. Therefore now, HW stats events are tested first, independent of netdevice type. The upshot is that as of this commit, mlxsw supports L3 HW stats work on GRE tunnels.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
