From cd8a84ad4622d4871d47bb92e2b6a5de8d0cfea7 Mon Sep 17 00:00:00 2001 From: Himanshu Agarwal Date: Thu, 21 Jul 2016 14:59:50 +0530 Subject: qcacld-3.0: Refactor support to get per chain rssi stats Propagation from qcacld-2.0 to qcacld-3.0. Add sanity check based on TLV len in addition to the check based on TLV tag id to ensure that if fw does not support or is not sending rssi stats then HOST does not process it at all.
