From: Ashok Raj Nagarajan <arnagara@qti.qualcomm.com> To: <ath10k@lists.infradead.org> Cc: <linux-wireless@vger.kernel.org>, <arnagara@codeaurora.org>, "Ashok Raj Nagarajan" <arnagara@qti.qualcomm.com> Subject: [PATCH] ath10k: add support for controlling tx power to a station Date: Tue, 14 Jun 2016 23:08:31 +0530 [thread overview] Message-ID: <1465925914-6404-1-git-send-email-arnagara@qti.qualcomm.com> (raw) This patch will add the support to control the transmit power for traffic to a station associated with the AP. Userspace provide the transmit power value in mBm units and the allowed range is from 0 to 70. Underlying FW will enforce that the maximum tx power will be based on the regulatory requirements. If the user given transmit power is greater than the allowed tx power in the given channel, then the FW will use the maximum tx power in the same channel. When 0 is sent to the FW as tx power, it will revert to the automatic tx power for the station.
