When multiple vif are in use (= one access point and one station), and
when the channels are different, it is necessary to enable power save on
station.
The firmware check that steps are done in the correct order:
- AP can't start if PS is not enable on the station
- PS can't set on the station before the association has finished
(= before the call set_bss_params)
Obviously, in add, when one of the interface disappears, it is necessary to
restore the power save status.
wfx_update_pm() is able to set the correct PS configuration. But it has
to be called at the right time:
1. before hif_start(), but after the channel configuration is known
2. after hif_set_bss_params()
3. after hif_reset()
Therefore, the call to wfx_update_pm() from wfx_add_interface() is too
early to address 1.
The call after hif_set_bss_params() already exists.
For the symmetry, the call from wfx_remove_interface() (that handle 3.)
is also relocated.

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.
