Date: Mon, 27 Apr 2020 15:40:19 +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 05/17] staging: wfx: fix CAB sent at the wrong time From: Jérôme Pouiller <jerome.pouiller@...abs.com> wfx_suspend_resume_mc() is called when the device is about to sent a DTIM. This is the right moment to enqueue Content After DTIM Beacon (CAB). However, wfx_suspend_resume_mc() is also called when the DTIM period ends. Until now, this event did also trig CAB. Note this issue did not have too much impact since when a CAB is sent outside of DTIM window, an error is reported by the firmware and mac80211 retries to send the data.
