Subject: [PATCH 07/12] staging: wfx: fix frame reordering
Date: Thu, 20 Aug 2020 17:58:53 +0200 [thread overview]
Message-ID: <20200820155858.351292-7-Jerome.Pouiller@silabs.com> (raw)
In-Reply-To: <20200820155858.351292-1-Jerome.Pouiller@silabs.com>
From: Jérôme Pouiller <jerome.pouiller@silabs.com>
When mac80211 debug is enabled, the trace below appears:
[60744.340037] wlan0: Rx A-MPDU request on aa:bb:cc:97:60:24 tid 0 result -524
This imply that ___ieee80211_start_rx_ba_session will prematurely exit
and frame reordering won't be enabled.
Fixes: e5da5fbd77411 ("staging: wfx: fix CCMP/TKIP replay protection")
