Tiny detail: putting a % in front of constants formats them nicer in the
html output.

I can see where you're coming from, but maybe this should be more like
ieee80211_driver_notify_disconnect() or something like that?

printk lines are allowed to pass 80 chars to make grep easier. Also I
really think this should be more like "Connection to AP %pM lost." or
something like that?

And I'm actually wondering now if using the same API is a good idea.
Yes, it makes some sense, but it's quite different yet? Maybe we should
have something like this:

static inline void ieee80211_beacon_loss(hw, vif)
{
	WARN_ON(hw->flags & IEEE80211_HW_CONNECTION_MONITOR);
	__ieee80211_beacon_connection_loss(vif);
}

static inline void ieee80211_connection_loss(hw, vif)
{
	WARN_ON(!(hw->flags & IEEE80211_HW_CONNECTION_MONITOR));
	__ieee80211_beacon_connection_loss(vif);
}

to make at least the external API easier to understand?
