Subject: [PATCH v5 4/7] wcn36xx: Add wcn36xx_smd_set_sta_vht_params()
Date: Thu, 10 Sep 2020 16:05:49 +0100	[thread overview]
Message-ID: <20200910150552.2178882-5-bryan.odonoghue@linaro.org> (raw)
In-Reply-To: <20200910150552.2178882-1-bryan.odonoghue@linaro.org>

This commit adds support for setting VHT parameters based on the declared
VHT capability bits in the VHT capability structure.

We cannot do 160MHz so VHT Channel width set should be zero.
