From 341203e78943236d4a8e4ca58d6a236195f0652e Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Sat, 2 Feb 2019 01:16:31 +0200 Subject: [PATCH] mac80211_hwsim: Support boottime in scan results This makes the age information for cfg80211 scan results more accurate and fixes issues with wpa_supplicant dropping "old" scan results (e.g., "wlan0: Own scan request started a scan in 0.000456 seconds") that looked like would have been received before a scan started due to the inaccuracy of the default timing mechanism for calculating the BSS entry age. This makes hwsim test cases significantly more robust to run.
