[ Upstream commit 6157ca0d6bfe437691b1e98a62e2efe12b6714da ] When mac80211 requests the low level driver to stop an ongoing Tx aggregation, the low level driver is expected to call ieee80211_stop_tx_ba_cb_irqsafe() to indicate that it is ready to stop the session. The callback in turn schedules a worker to complete the session tear down, which in turn also handles the relevant state for the intermediate Tx queue. However, as this flow in asynchronous, the intermediate queue should be stopped and not continue servicing frames, as in such a case frames that are dequeued would be marked as part of an aggregation, although the aggregation is already been stopped. Fix this by stopping the intermediate Tx queue, before calling the low level driver to stop the Tx aggregation.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
