Subject: [PATCH] iwlwifi: disable tx on beacon update notification
On beacon change update notification from mac we are not disabling
the tx in adhoc mode. Mac sends BSS_CHANGED_BEACON_ENABLED when
station leaves IBSS. Driver should indicate uCode to not to send
anything on receiving this notification.
Functionality to indicate uCode is duplicated across
two notifications so created a common function called iwl_set_no_assoc.
Fix the issue at
http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2133.
