517357c685 cfg80211: assimilate and export ieee80211_bss_get_ie
This function from mac80211 seems generally useful, and
I will need it in cfg80211 soon.

0eb14647fc cfg80211: reset auth algorithm
When the interface is brought down, we need to
reset the auth algorithm because wpa_supplicant
doesn't reset it, and then we fail to use shared
key auth when required later.

e45cd82ace cfg80211: send events for userspace SME
When the userspace SME is in control, we are currently not sending
events, but this means that any userspace applications using wext
or nl80211 to receive events will not know what's going on unless
they can also interpret the nl80211 assoc event. Since we have all
the required code, let the SME follow events from the userspace
SME, this even means that you will be refused to connect() while
the userspace SME is in control and connected.

ab1faead50 mac80211: remove dead code, clean up
With mac80211 now always controlled by an external SME,
a lot of code is dead -- SSID, BSSID, channel selection
is always done externally, etc. Additionally, rename
IEEE80211_STA_TKIP_WEP_USED to IEEE80211_STA_DISABLE_11N

ac00326e9d mac80211: re-add HT disabling
The IEEE80211_STA_TKIP_WEP_USED flag is used internally to

b23aa676ab cfg80211: connect/disconnect API
This patch introduces the cfg80211 connect/disconnect API.
The goal here is to run the AUTH and ASSOC steps in one call.
This is needed for some fullmac cards that run both steps
directly from the target, after the host driver sends a
connect command.

Additionally, all the new crypto parameters for connect()
are now also valid for associate() -- although associate
requires the IEs to be used, the information can be useful
for drivers and should be given.

aff89a9b90 cfg80211: introduce nl80211 testmode command
This introduces a new NL80211_CMD_TESTMODE for testing
and calibration use with nl80211. There's no multiplexing
like like iwpriv had, and the command is not available by
default, it needs to be explicitly enabled in Kconfig and
shouldn't be enabled in most kernels.

The command requires a wiphy index or interface index to
identify the device to operate on, and the new TESTDATA
attribute. There also is API for sending replies to the
command, and testmode multicast messages (on a testmode
multicast group).

I've also updated mac80211 to be able to pass through the
command to the driver, since it itself doesn't implement
the testmode command.

Additionally, to give people an idea of how to use the
command, I've added a little code to hwsim that makes use
of the new command to set the powersave mode, this is
currently done via debugfs and should remain there, and
the testmode command only serves as an example of how to
use this best -- with nested netlink attributes in the
TESTDATA attribute. A hwsim testmode tool can be found at
http://git.sipsolutions.net/hwsim.git/. This tool is BSD
licensed so people can easily use it as a basis for their
own internal fabrication and validation tools.

0575606b08 mac80211: tell SME about real auth state
When the auth algorithm is rejected, but we don't have
another one to try, we will eventually retry but that
isn't useful -- we'll then do it again and again until
we eventually give up. Instead, we should let the SME
know and go into disabled state. The same applies for
situations where the AP rejects with any other status
code.

Additionally, when trying the next auth algorithm, we
should reset the auth_tries so that just a single lost
frame doesn't lead to us giving up on the third auth
algorithm.

df2b35b65b wext: allow returning NULL stats
Currently, wext drivers cannot return NULL for stats even though
that would make the ioctl return -EOPNOTSUPP because that would
mean they are no longer listed in /proc/net/wireless. This patch
changes the wext core's behaviour to list them if they have any
wireless_handlers, but only show their stats when available, so
that drivers can start returning NULL if stats are currently not
available, reducing confusion for e.g. IBSS.

orinoco_private, which we encapsulate in the inline function ndev_priv.
Most of the remaining calls to netdev_priv are thus replaced by
ndev_priv.
