If the user wants to scan using a vif configured as AP,
cfg80211 must give him a chance to do it, even if this
will disrupt the stations performance due to off-channel
scanning. To do so, this patch adds a 'force' flag to the
SCAN_TRIGGER command which tells cfg80211 to perform the
scanning operation even if the vif is an AP and the
beaconing has already started.

Currently, a user is allowed to choose a HT operating channel
with WEP when creating an IBSS network. WEP is not allowed
in HT configuration - this patch ensures that such requests
are denied.

The include file linux/ieee80211.h contains three definitions for
the same thing in enum ieee80211_eid due to historic changes:
/* Information Element IDs */
enum ieee80211_eid {
:
WLAN_EID_WPA = 221,
WLAN_EID_GENERIC = 221,
WLAN_EID_VENDOR_SPECIFIC = 221,
:
};
The standard refers to this as "vendor specific" element so the
other two definitions are better not used. This patch changes the
wireless drivers to use one definition, ie. WLAN_EID_VENDOR_SPECIFIC.

Initialization of beacon transmission in IBSS mode depends
on whether a new BSS is being created or joined. When joining
an existing IBSS network, beaconing has to start only after
a TSF-sync has happened - this is explained in 11.1.4.
Introduce a new parameter in the BSS information structure to
indicate creator/joiner mode.

[set feature flag only if software scan is used]
Signed-off-by: Johannes Berg <johannes.berg@intel.com>
Add an NL80211_SCAN_FLAG_FLUSH flag that causes old bss cache
entries to be flushed on scan completion. This is useful for
collecting guaranteed fresh scan/survey result (e.g. on resume).
For normal scan, flushing only happens on successful completion
of a scan; i.e. it does not happen if the scan is aborted.
For scheduled scan, previous scan results are flushed everytime
when we get new scan results.
This feature is enabled by default. Drivers can disable it by
unsetting the NL80211_FEATURE_SCAN_FLUSH flag.

[invert polarity of feature flag to account for old kernels]
Signed-off-by: Johannes Berg <johannes.berg@intel.com>
The next patch will introduce a flag that is set
by default in cfg80211 so drivers and mac80211
need to use |= to set features they have so that
they don't clear the already-set feature.
We could set the flag in wiphy_register() instead
of wiphy_new() to avoid this patch, but then the
drivers couldn't *unset* flags they don't want to
use even though the implementation is generic.
