Subject: [RFC 0/2] mac80211: Add new interface type for OCB (Outside the Context of a BSS) mode

The IEEE 802.11p amendment defines a procedure for data frames
transmission by an STA that is not a member of a BSS. Such data
frames are defined as being transmitted "outside the context of a
BSS" (this is allowed only if the MIB variable dot11OCBActivated
is true).  This patchset adds new interface type (NL80211_IFTYPE_OCB)
for an STA in the OCB mode.

When an OCB mode is used, all the STAs communicate with each
other without the need for a coordinator. In such case no beacons
are sent and BSSID is set to wildcard (all 1's). Every STA receives
all frames from every STA in range and transmits to every STA tuned
to the same channel. The communication is taking place in a reserved
frequency band (5.9 GHz).
