From 94bc94b2068f374b369a395411a365c88cc907d6 Mon Sep 17 00:00:00 2001 From: Purushottam Kushwaha Date: Thu, 12 May 2022 13:04:54 +0530 Subject: [PATCH] Add QCA vendor attribute for DO_ACS to allow using existing scan entries Add a new QCA vendor attribute QCA_WLAN_VENDOR_ATTR_ACS_LAST_SCAN_AGEOUT_TIME to QCA_NL80211_VENDOR_SUBCMD_DO_ACS and opportunistically optimize time taken for ACS scan. Avoid scanning the channels which were scanned within last QCA_WLAN_VENDOR_ATTR_ACS_LAST_SCAN_AGEOUT_TIME milliseconds and use scan results from the scan results cache for ACS scoring. For other channels, perform ACS scan and use the received scan results.
