Dave Ertman fd7f7a8ad3 ice: Fix VF Reset paths when interface in a failed over aggregate 
[ Upstream commit 9f74a3dfcf ]

There is an error when an interface has the following conditions:
- PF is in an aggregate (bond)
- PF has VFs created on it
- bond is in a state where it is failed-over to the secondary interface
- A VF reset is issued on one or more of those VFs

The issue is generated by the originating PF trying to rebuild or
reconfigure the VF resources.  Since the bond is failed over to the
secondary interface the queue contexts are in a modified state.

To fix this issue, have the originating interface reclaim its resources
prior to the tear-down and rebuild or reconfigure.  Then after the process
is complete, move the resources back to the currently active interface.

There are multiple paths that can be used depending on what triggered the
event, so create a helper function to move the queues and use paired calls
to the helper (back to origin, process, then move back to active interface)
under the same lag_mutex lock.

Fixes: 1e0f9881ef ("ice: Flesh out implementation of support for SRIOV on bonded interface")

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.
