Currently, recovery flag is set immediately upon firmware exit but tx queues are stopped once firmware arrives back and is ready which is during ath11k_core_restart. Once ieee80211 hw restart is completed, tx queues are resumed. If during the time delta between firmware exit and firmware ready, mac80211 send packets, currently ath11k will drop it since recovery flag will be set. But warning prints will come - "ath11k c000000.wifi: failed to transmit frame -108" If more tx packets are there, this could lead to flooding of above print. However, actually tx queues should be stopped immediately when firmware leaves. This will prevent packets to get dropped when firmware is recovering. Add fix to stop tx queues immediately after firmware exit.

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.
