David S. Miller 09bef83268 Merge branch 'stmmac-vlan-priority-rx-steering' 
Ong Boon Leong says:

====================
stmmac: add VLAN priority based RX steering

The current tc flower implementation in stmmac supports both L3 and L4
filter offloading. This patch adds the support of VLAN priority based
RX frame steering into different Rx Queues.

The patches have been tested on both configuration test (include L3/L4)
and traffic test (multi VLAN ping streams with RX Frame Steering) below:-

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.
