X-Git-Tag: v3.9-rc1~139^2~31^2^2~12^2~12

cfg80211: track hidden SSID networks properly

Currently, cfg80211 will copy beacon IEs from a previously
received hidden SSID beacon to a probe response entry, if
that entry is created after the beacon entry. However, if
it is the other way around, or if the beacon is updated,
such changes aren't propagated.

Fix this by tracking the relation between the probe
response and beacon BSS structs in this case.

In case drivers have private data stored in a BSS struct
and need access to such data from a beacon entry, cfg80211
now provides the hidden_beacon_bss pointer from the probe
response entry to the beacon entry.
