Spectrum machines support L3 stats by binding a counter to a RIF, a hardware object representing a router interface. Recognize the netdevice notifier events, NETDEV_OFFLOAD_XSTATS_*, to support enablement, disablement, and reporting back to core. As a netdevice gains a RIF, if L3 stats are enabled, install the counters, and ping the core so that a userspace notification can be emitted. Similarly, as a netdevice loses a RIF, push the as-yet-unreported statistics to the core, so that they are not lost, and ping the core to emit userspace notification.

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.
