When an RX block-ack session times out, the firmware, which offloads RX reordering but not the BA session negotiation, stops the session but doesn't send a DELBA. This causes the the session to remain active in the remote device, so no more BA sessions will be established, causing a severe throughput degradation due to the lack of aggregation. Use the new ieee80211_rx_ba_timer_expired API when the ba session timer expires, since this will tear down the ba session and also send a delba. The previous API used is intended for drivers that offload the addba/delba negotiation, but not the rx reordering, while our driver does the opposite. This patch depends on "mac80211: add api to start ba session timer expired flow". Signed-off-by: Naftali Goldstein <naftali.goldstein@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
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.
