Subject: mac80211: reconfig bss_info_changed only if beaconing
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8da349329ae52462253052f804ef30d086c9911a;p=linux-beck.git

mac80211: reconfig bss_info_changed only if beaconing

For AP/IBSS/mesh interfaces, call the driver to reconfigure
bss_info_changed only if the interface was beaconing before
suspend, otherwise we call the driver and it might interpret
the change as going from enabled to disabled.
