Subject: [PATCH 07/11] ath10k_sdio: fix rssi indication
Date: Sat, 30 Sep 2017 23:07:44 +0530 [thread overview]
Message-ID: <1506793068-27445-8-git-send-email-alagusankar@silex-india.com> (raw)
In-Reply-To: <1506793068-27445-1-git-send-email-alagusankar@silex-india.com>
From: Alagu Sankar <alagusankar@silex-india.com>
Receive descriptor of sdio device does not include the rssi. notify
mac80211 accordingly. Without the fix, the rssi value indicated by
iw changes between the actual value and -95.
