Subject: [PATCH AUTOSEL 4.19 014/258] ath9k: dynack: use authentication messages for 'late' ack
Date: Mon, 28 Jan 2019 10:55:20 -0500 [thread overview]
Message-ID: <20190128155924.51521-14-sashal@kernel.org> (raw)
In-Reply-To: <20190128155924.51521-1-sashal@kernel.org>
From: Lorenzo Bianconi <lorenzo.bianconi@redhat.com>
[ Upstream commit 3831a2a0010c72e3956020cbf1057a1701a2e469 ]
In order to properly support dynack in ad-hoc mode running
wpa_supplicant, take into account authentication frames for
'late ack' detection. This patch has been tested on devices
mounted on offshore high-voltage stations connected through
~24Km link
