commitb719ebc37aupstream. Serialize the ath10k implementation of the wake_tx_queue ops. ath10k_mac_op_wake_tx_queue() must not run concurrent since it's using ieee80211_txq_schedule_start(). The intend of this patch is to sort out an issue discovered in the discussion referred to by the Link tag. I can't test it with real hardware and thus just implemented the per-ac queue lock Felix suggested. One obvious alternative to the per-ac lock would be to bring back the txqs_lock commitbb2edb7335("ath10k: migrate to mac80211 txq scheduling") dropped.

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.
