From 41bb73eeac5ff5fb217257ba33b654747b3abf11 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 29 Oct 2008 01:09:37 +0100 Subject: mac80211: remove SSID driver code Remove the SSID from the driver API since now there is no driver that requires knowing the SSID and I think it's unlikely that any hardware design that does require the SSID will play well with mac80211. This also removes support for setting the SSID in master mode which will require a patch to hostapd to not try. Signed-off-by: Johannes Berg Signed-off-by: John W.
