This patch enables macvlan offloads for i40e. The idea is to use channels as macvlan interfaces. The channels are VSIs of type VMDQ. When the first macvlan is created, the maximum number of channels possible are created. From then on, as a macvlan interface is created, a macvlan filter is added to these already created channels (VSIs). This patch utilizes subordinate device traffic classes to make queue groups(channels) available for an upper device like a macvlan. Steps to configure macvlan offloads: 1. ethtool -K ethx l2-fwd-offload on 2. ip link add link ethx name macvlan1 type macvlan 3. ip addr add <address> dev macvlan1 4. ip link set macvlan1 up Signed-off-by: Harshitha Ramamurthy <harshitha.ramamurthy@intel.com> Tested-by: Andrew Bowers <andrewx.bowers@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
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.
