Subject: mac80211: silently accept deletion of non-existant key
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=be892471c42f70e47541e42b8dba7ff91cebd026;p=openwrt%2Fstaging%2Fblogic.git

mac80211: silently accept deletion of non-existant key

Otherwise, 'iwconfig wlan0 key off' with no key set results in:

	Error for wireless request "Set Encode" (8B2A) :
	    SET failed on device wlan0 ; No such file or directory.
