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.

The way I initially thought we could do wireless extensions
is by making all the compat code in cfg80211 be independent
of CONFIG_WIRELESS_EXT, but this is turning out to not be
feasible. Therefore, fix the Kconfig help text and make the
option default to yes, so people won't get a nasty surprise
when mac80211 will get rid of its 'select WIRELESS_EXT' any
time now.

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.

Initialise and register a wiphy.
Store the orinoco_private structure in the new wiphy, and use the
net_device private area to store the wireless_dev. This results in a
change to the way we navigate from a net_device to the driver private
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.
We can immediately rely on cfg80211 to handle SIOCGIWNAME, so
orinoco_ioctl_getname is removed.

during a given scan, and some hardware (notably iwlwifi) can
only scan a limited number of channels at a time. To prevent
any overflows, simply disallow scanning any channel multiple

userspace ABI, but the only user, wpa_supplicant, never asks

Within mac80211, we often need to copy the rx status into

in there to start with. This patch changes the API so that
drivers are expected to pass the RX status in skb->cb, now
accessible as IEEE80211_SKB_RXCB(skb). It also updates all
drivers to pass the rx status in there, but only by making
them memcpy() it into place before the call to the receive
function (ieee80211_rx(_irqsafe)). Each driver can now be
