On netdev down event, nf_flow_table_cleanup() is called for the relevant
device and it cleans all the tables that are on that device.
If one of those tables has hardware offload flag,
nf_flow_table_iterate_cleanup flushes hardware and then runs the gc.
But the gc can queue more hardware work, which will take time to execute.
Instead first add the work, then flush it, to execute it now.

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.
