Subject: [PATCH v5.4] iwlwifi: fw: don't send GEO_TX_POWER_LIMIT command to FW
|
|
version 36
|
|
Sender: linux-wireless-owner@vger.kernel.org
|
|
Precedence: bulk
|
|
List-ID: <linux-wireless.vger.kernel.org>

X-Mailing-List: linux-wireless@vger.kernel.org

|
|
From: Luca Coelho <luciano.coelho@intel.com>
|
|
|
|
The intention was to have the GEO_TX_POWER_LIMIT command in FW version
|
|
36 as well, but not all 8000 family got this feature enabled. The
|
|
8000 family is the only one using version 36, so skip this version
|
|
entirely. If we try to send this command to the firmwares that do not
|
|
support it, we get a BAD_COMMAND response from the firmware.
|
|
|
|
This fixes https://bugzilla.kernel.org/show_bug.cgi?id=204151.
