ieee80211_reconfig() of mac80211 is the main function for recovery of each ieee80211_hw and ath11k, and ath11k_core_reconfigure_on_crash() is the main function for recovery of ath11k_base, it has more than one ieee80211_hw and ath11k for each ath11k_base, so it need to add synchronization between them, otherwise it has many issue. For example, when ath11k_core_reconfigure_on_crash() is not complete, mac80211 send a hw scan request to ath11k, it leads firmware crash, because firmware has not been initialized at that moment, firmware is only finished downloaded and loaded, it can not receive scan command.

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.
