Linux kernel source tree

Implement the following notifications towards drivers: - NEXTHOP_EVENT_REPLACE, when a resilient nexthop group is created. - NEXTHOP_EVENT_BUCKET_REPLACE any time there is a change in assignment of next hops to hash table buckets. That includes replacements, deletions, and delayed upkeep cycles. Some bucket notifications can be vetoed by the driver, to make it possible to propagate bucket busy-ness flags from the HW back to the algorithm. Some are however forced, e.g. if a next hop is deleted, all buckets that use this next hop simply must be migrated, whether the HW wishes so or not. - NEXTHOP_EVENT_RES_TABLE_PRE_REPLACE, before a resilient nexthop group is replaced. Usually the driver will get the bucket notifications as well, and could veto those. But in some cases, a bucket may not be migrated immediately, but during delayed upkeep, and that is too late to roll the transaction back. This notification allows the driver to take a look and veto the new proposed group up front, before anything is committed.

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.
