Ido Schimmel says: ==================== mlxsw: Preparations for resilient nexthop groups This patchset contains preparations for resilient nexthop groups support in mlxsw. A follow-up patchset will add support and selftests. Most of the patches are trivial and small to make review easier. Patchset overview: Patch #1 removes RTNL assertion in nexthop notifier block since it is not needed. The assertion will trigger when mlxsw starts processing notifications related to resilient groups as not all are emitted with RTNL held. Patches #2-#9 gradually add support for nexthops with trap action. Up until now mlxsw did not program nexthops whose neighbour entry was not resolved. This will not work with resilient groups as their size is fixed and the nexthop mapped to each bucket is determined by the nexthop code. Therefore, nexthops whose neighbour entry is not resolved will be programmed to trap packets to the CPU in order to trigger neighbour resolution. Patch #10 is a non-functional change to allow for code reuse between regular nexthop groups and resilient ones. Patch #11 avoids unnecessary neighbour updates in hardware. See the commit message for a detailed explanation. Patches #12-#14 add support for additional nexthop group sizes that are supported by Spectrum-{2,3} ASICs. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> |

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.
