Subject: [PATCH] UBUNTU: Cause SoftMac to emit an association event when setting ESSID.
Bug: https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/103768

Signed-off-by: Tim Gardner <tim.gardner at canonical.com>

wpa_supplicant assumes that it will get an association event whenever it sets ESSID.
This patch causes SoftMac to emit an association event even if its already associated
and setting ESSID will cause no change in association state.
