Subject: [PATCH AUTOSEL 5.5 07/35] iwlwifi: consider HE capability when setting LDPC
Date: Mon, 6 Apr 2020 20:00:29 -0400 [thread overview]
Message-ID: <20200407000058.16423-7-sashal@kernel.org> (raw)
In-Reply-To: <20200407000058.16423-1-sashal@kernel.org>
From: Mordechay Goodstein <mordechay.goodstein@intel.com>
[ Upstream commit cb377dfda1755b3bc01436755d866c8e5336a762 ]
The AP may set the LDPC capability only in HE (IEEE80211_HE_PHY_CAP1),
but we were checking it only in the HT capabilities.
If we don't use this capability when required, the DSP gets the wrong
configuration in HE and doesn't work properly.
