From: John W. Linville Date: Tue, 30 Sep 2008 21:17:26 +0000 (-0400) Subject: wireless: remove NETWORK_EMPTY_ESSID flag X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c5d3dce875ef055ed9b14f169cc967cc2c8faf1f;p=openwrt%2Fstaging%2Fblogic.git wireless: remove NETWORK_EMPTY_ESSID flag It is unnecessary and of questionable value. Also remove is_empty_ssid, as it is also unnecessary. Signed-off-by: John W.
