f63b8b2ec9 wiphy: Fix open network connection 
Authenticate event on wiphy mlme notification does not provide
enough information on which network/bss authentication command
was sent. BSS and network information is required to send associate
command to AP. So cache bss pointer in netdev struct and retrieve
on wiphy mlme notifications.

6ddd2b894d scan: SSID security check was missing values 
Refactoring SSID security check function to work properly so that
it can differentiate AP security setting correctly.

Denis Kenzior
26010b8459 wiphy: Optimize scanning data structures 
Instead of storing multiple copies of the same BSS (one hanging off the
netdev object and one hanging off the network object), we instead store
the BSS list only on the netdev object.

The network object gets a pointer to the BSS structure on the netdev
list.  As a side effect, the BSS list is always sorted properly.

0303a095aa wiphy: Remove unneeded variable 
Instead of always mallocing space for the ssid array, and then freeing
it in most circumstances, do the opposite.  Only allocate the array once
it is actually needed.  This has the side effect of removing an unneeded
variable and making the code simpler.

d27c947209 wiphy: expose network objects instead of BSSes 
The idea here is that network object will contain a list of BSS
that have the same SSID and security setting. From user point of view,
we will connect to a certain SSID instead of connecting directly to
a BSS. We pick the best BSS automatically from the BSS list when
connecting to a SSID.

8f946c0cdc eapol: Change function signatures 
The frame which comes in is an EAPoL-key frame, thus changing the name
accordingly (as well as the parameter names).

Also, returning the cast pointer instead of a boolean is easier to
use as there won't be any need to perform the cast ourselves afterward

Tomasz Bursztyka
e02f02fa69 mpdu: Change the validation function signature

use as there won't be any need to perform the cast ourselves afterward

672be730c3 wiphy: Add scheduled scan support 
Add rudimentary support for mac80211 scheduled scan feature.
This is done so that kernel support for task called "Bind
NL80211_CMD_START_SCHED_SCAN to netlink socket" from TODO
file can be tested. The current scan interval is set to 60
seconds which is probably too fast for the final version.

051f49ea85 wiphy: Tweak netdev structure creation order 
Because none of the attributes are assigned until after the DeviceAdded
signal is emitted, the signal appears with invalid properties.  For now,
move the netdev structure fill-out into the if statement.

If the netdev attributes can change, then these need to be handled
separately and appropriate signals to be sent.
