Jacob Keller f8af5bf5b4 ice: reject VF attempts to enable head writeback
The virtchnl interface provides a mechanism for a VF driver to request
head writeback support. This feature is deprecated as of AVF 1.0, but
older versions of a VF driver may still attempt to request the mode.

Since the ice hardware does not support head writeback, we should not
accept Tx queue configuration which attempts to enable it.

Currently, the driver simply assumes that the headwb_enabled bit will
never be set.

If a VF driver does request head writeback, the configuration will
return successfully, even though head writeback is not enabled. This
leaves the VF driver in a non functional state since it is assuming to
be operating in head writeback mode.

Fix the PF driver to reject any attempt to setup headwb_enabled.

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.

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.
