Submitting AP probe/null during suspend can cause unexpected disconnect on resume because of timeout waiting for ack status: wlan0: Failed to send nullfunc to AP 11:22:33:44:55:66 after 500ms, disconnecting This is especially the case when we enter suspend when a scan is ongoing, indeed, scan is cancelled from __ieee80211_suspend, leading to a corresponding (aborted) scan complete event, which in turn causes the submission of an immediate monitor null frame (restart_sta_timer). The corresponding packet or ack will not be processed before resuming, causing a timeout & disconnect on resume. Delay the AP probing when suspending/suspended.

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.
