Ido Schimmel says: ==================== mlxsw: spectrum: acl: Introduce ERP sharing by multiple masks Jiri says: The Spectrum-2 hardware has limitation number of ERPs per-region. In order to accommodate more masks than number of ERPs, the hardware supports to insert rules with delta bits. By that, the rules with masks that differ in up-to 8 consecutive bits can share the same ERP. Patches 1 and 2 fix couple of issues that would appear in existing selftests after adding delta support Patch 3 introduces a generic object aggregation library. Now it is static, but it will get extended for recalculation of aggregations in the future in order to reach more optimal aggregation. Patch 4 just simply converts existing ERP code to use the objagg library instead of a rhashtable. Patches 5-9 do more or less small changes to prepare ground for the last patch. Patch 10 fills-up delta callbacks of objagg library and utilizes the delta bits for rule insertion. The last patch adds selftest to test the mlxsw Spectrum-2 delta flows. ==================== 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.
