From cb3a8eec0e66edfe8db7d3b3bf19d25745bae3c3 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Wed, 11 Feb 2009 17:14:43 -0500 Subject: cfg80211: age scan results on resume Scanned BSS entries are timestamped with jiffies, which doesn't increment across suspend and hibernate. On resume, every BSS in the scan list looks like it was scanned within the last 10 seconds, irregardless of how long the machine was actually asleep. Age scan results on resume with the time spent during sleep so userspace has a clue how old they really are. Signed-off-by: Dan Williams Signed-off-by: John W.
