[ Upstream commit c470bdc1aaf36669e04ba65faf1092b2d1c6cabe ] Apparently, some APs are buggy enough to send a zeroed WMM IE. Don't WARN on this since this is not caused by a bug on the client's system. This aligns the condition of the WARNING in drv_conf_tx with the validity check in ieee80211_sta_wmm_params. We will now pick the default values whenever we get a zeroed WMM IE. This has been reported here: https://bugzilla.kernel.org/show_bug.cgi?id=199161 Fixes: f409079bb678 ("mac80211: sanity check CW_min/CW_max towards driver") Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
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.
