.ndo_set_rx_mode gets called in process context, but while holding the addr_list spinlock. Which means we currently can't sleep while re-programming the HW, and need to poll for IO completion. That's bad, in particular since receiving the cmd response can fail silently and we're then polling until the timeout hits. As a first step towards eliminating the IO completion polling, run the RX modeset from a work element and only take the addr_list lock while updating the RX mode address cache.

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.
