When the device is removed, idpf is supposed to make certain virtchnl
requests e.g. VIRTCHNL2_OP_DEALLOC_VECTORS and VIRTCHNL2_OP_DESTROY_VPORT.
However, this does not happen due to the referenced commit introducing
virtchnl transaction manager and placing its deinitialization before those
messages are sent. Then the sending is impossible due to no transactions
being available.
Lack of cleanup can lead to the FW becoming unresponsive from e.g.
unloading-loading the driver and creating-destroying VFs afterwards.
Move transaction manager deinitialization to after other virtchnl-related
cleanup is done.
Fixes: 34c21fa894 ("idpf: implement virtchnl transaction manager")

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 reStructuredText 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.
