Subject: mac80211: add beacon configuration via cfg80211
This patch implements the cfg80211 hooks for configuring beaconing
on an access point interface in mac80211. While doing so, it fixes
a number of races that could badly crash the machine when the
beacon is changed while being requested by the driver.
Signed-off-by: Johannes Berg <johannes@sipsolutions.net>
---
The dtim_count field should possibly also be part of the beacon
structure, but the possible race there doesn't really matter,
worst thing is that one beacon will be sent with a wrong dtim
count if (and only if) userspace changes the dtim period during
operation.

Subject: cfg80211/nl80211: implement station attribute retrieval
After a station is added to the kernel's structures, userspace
has to be able to retrieve statistics about that station, especially
whether the station was idle and how much bytes were transferred
to and from it. This adds the necessary code to nl80211.
