On older devices like X710 and X722, the VF's ARQLEN register is cleared on reset, so the VF driver uses that register to detect an unannounced reset. Unfortunately, on devices controlled by ice, this register is NOT cleared on reset. This causes the VF to miss resets, and even on properly-announced resets, the VF driver complains that it didn't see the reset. To fix this, we'll do it in software. When we handle a VF reset (whether triggered by software or VFLR), clear this register after the HW reset is complete.

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.
