ibmvnic: Introduce affinity hint support
This is a patchset to do 3 things to improve ibmvnic performance:
1. Assign affinity hints to ibmvnic queue irq's
2. Update affinity hints on cpu hotplug events
3. Introduce transmit packet steering (XPS)
NOTE: If irqbalance is running, you need to stop it from overriding
our affinity hints. To do this you can do one of:
- systemctl stop irqbalance
- ban the ibmvnic module irqs
- you must have the latest irqbalance v9.2, the banmod argument was broken before this
- in /etc/sysconfig/irqbalance -> IRQBALANCE_ARGS="--banmod=ibmvnic"
- systemctl restart irqbalance

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.
