Ido Schimmel says:

====================
mlxsw: Make driver more robust

In recent months we fixed several bugs in the driver that could have
been avoided by re-evaluating some of the involved code paths and by
introducing relevant and comprehensive test cases.

This patchset tries to do that by introducing a set of small and mostly
non-functional changes in addition to a new test. I have further
improvements in mind, but they can be done in a different set.

Patch #1 makes sure we correctly sanitize upper devices of a VLAN
interface.

Patch #2 removes an unexpected behavior from the driver, in which routes
configured on a VLAN interface will cease being offloaded after certain
operations.

Patch #3 is a small cleanup.

Patch #4 simplifies the driver by removing reference counting from VLAN
entries configured on a port.

Patches #5-#6 simplify linking/unlinking from a bridge, especially when
LAG and VLAN devices are involved. They make both operations symmetric
even when ports are unlinked from a bridged LAG device.

Patch #7-#9 make router interface (RIF) deletion more robust by removing
reliance on device chain to indicate whether a NETDEV_DOWN event in the
inet{,6}addr notification chains should be processed. This is due to the
fact that IP addresses can be flushed from a netdev after it was
unlinked from its lower device.

Patch #10 adds a new test to for valid and invalid configurations over
mlxsw ports. Some of the test cases are derived from recent fixes. I
expect that more test cases will be added over time.

README

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.
