Date: Wed, 1 Apr 2020 13:03:47 +0200 From: Jerome Pouiller <Jerome.Pouiller@...abs.com> To: devel@...verdev.osuosl.org, linux-wireless@...r.kernel.org Cc: netdev@...r.kernel.org, linux-kernel@...r.kernel.org, Greg Kroah-Hartman <gregkh@...uxfoundation.org>, Kalle Valo <kvalo@...eaurora.org>, "David S . Miller" <davem@...emloft.net>, Jérôme Pouiller <jerome.pouiller@...abs.com> Subject: [PATCH 14/32] staging: wfx: do not use link_map_cache to track CAB From: Jérôme Pouiller <jerome.pouiller@...abs.com> Since we do not track power save status of the stations anymore, link_map_cache is now only used to track "Content After (DTIM) Beacon". We prefer to rely on flags from tx_info. So we will be able to drop link_map_cache.
