Hmm, this is very vague. Are you sure it does what you think it does?
Some drivers like wl12xx might not trigger the beacon loss function for
every beacon, instead aggregating things. I implemented this in iwlwifi
once and it would only tell mac80211 roughly every 20 beacons about
missed ones...

This should at least be documented, but I fear it makes the value rather
useless in the general case.
