Subject: [PATCH v5.6 2/7] iwlwifi: consider HE capability when setting LDPC
Date: Fri,  6 Mar 2020 15:16:22 +0200	[thread overview]
Message-ID: <iwlwifi.20200306151128.492d167c1a25.I1ad1353dbbf6c99ae57814be750f41a1c9f7f4ac@changeid> (raw)
In-Reply-To: <20200306131627.503176-1-luca@coelho.fi>

From: Mordechay Goodstein <mordechay.goodstein@intel.com>

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.
