From 83f5e2cf79390f7ca909b7035dd415230257cc4d Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 17 Jun 2009 17:41:49 +0200 Subject: [PATCH] cfg80211: prohibit scanning the same channel more than once It isn't very useful to scan the same channel more than once during a given scan, and some hardware (notably iwlwifi) can only scan a limited number of channels at a time. To prevent any overflows, simply disallow scanning any channel multiple times in a given scan command. This is a small change in the userspace ABI, but the only user, wpa_supplicant, never asks for a scan with the same frequency listed twice. Signed-off-by: Johannes Berg Signed-off-by: John W.
