ROC event when CMD_FRAME duration expires

[James Prestwood <james.prestwood@linux.intel.com>]

Hi,

I see that the event CMD_CANCEL_REMAIN_ON_CHANNEL is emitted when a
CMD_REMAIN_ON_CHANNEL duration expires, but this is not true for
CMD_FRAME when sending offchannel and providing a duration. I see
wpa_supplicant handles this with its own timeout, but couldn't the same
event be emitted for CMD_FRAME if the duration expires?

Looking in mac80211/offchannel.c: ieee80211_roc_notify_destroy:

if (!roc->mgmt_tx_cookie)
	cfg80211_remain_on_channel_expired(&roc->sdata->wdev,
					   roc->cookie, roc->chan,
					   GFP_KERNEL);

In the case of CMD_FRAME, mgmt_tx_cookie is set, so this event does not
get emitted. Could the same expire event be emitted when mgmt_tx_cookie
is set as well? This would eliminate the need for userspace to keep a
timeout tracking this.

If this is ok I can send a patch (Looks like all I would need to do is
remove the if, and include the correct cookie, roc->cookie or roc-
>mgmt_tx_cookie).

Thanks,
James
