commit 6e6026f2dd2005844fb35c3911e8083c09952c6c upstream.
The Intel I211 Ethernet Controller supports 2 Receive Side Scaling (RSS)
queues. It should not be excluded from having this feature enabled.
Via commit c883de9fd787 ("igb: rename igb define to be more generic")
E1000_MRQC_ENABLE_RSS_4Q was renamed to E1000_MRQC_ENABLE_RSS_MQ to
indicate that this is a generic bit flag to enable queues and not
a flag that is specific to devices that support 4 queues
The bit flag enables 2, 4 or 8 queues appropriately depending on the part.
Tested with a multicore CPU and frames were then distributed as expected.
This issue appears to have been introduced because of confusion caused
by the prior name.

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.
