David S. Miller ebe023a424 mlx5e-updates-2018-07-27 (Vxlan updates)
This series from Gal and Saeed provides updates to mlx5 vxlan implementation.
 
 Gal, started with three cleanups to reflect the actual hardware vxlan state
 - reflect 4789 UDP port default addition to software database
 - check maximum number of vxlan  UDP ports
 - cleanup an unused member in vxlan work
 
 Then Gal provides performance optimization by replacing the
 vxlan radix tree with a hash table.
 
 Measuring mlx5e_vxlan_lookup_port execution time:
 
                       Radix Tree   Hash Table
      --------------- ------------ ------------
       Single Stream   161 ns       79  ns (51% improvement)
       Multi Stream    259 ns       136 ns (47% improvement)
 
     Measuring UDP stream packet rate, single fully utilized TX core:
     Radix Tree: 498,300 PPS
     Hash Table: 555,468 PPS (11% improvement)
 
 Next, from Saeed, vxlan refactoring to allow sharing the vxlan table
 between different mlx5 netdevice instances like PF and VF representors,
 this is done by making mlx5 vxlan interface more generic and decoupling
 it from PF netdevice structures and logic, then moving it into mlx5 core
 as a low level interface so it can be used by VF representors, which is
 illustrated in the last patch of the serious.

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
