[PATCH 0/4] 802.11p OCB mode

[Rostislav Lisovy]

The IEEE 802.11p amendment (already part of IEEE 802.11-2012)
specifies usage of 5 and 10 MHz wide channels in 5.9GHz band for
vehicular environment. All the 802.11p compliant devices should
be set to the newly added operation mode -- OCB (Outside the
Context of a BSS). No authentication/association is necessary to
communicate. The only parameter to be configured is the channel
(central frequency and bandwidth) to communicate on. The channel
has to be known a priori. It is set during the 'ocb join'
operation (sent via netlink message from user-space).

This patchset adds the OCB mode, OCB join and leave handling
(nl80211, cfg80211, mac80211), 802.11p EDCA parameters
modification, RX and TX path (for unicast/broadcast messages).

What aspects are ignored for now:
* Rate control -- We limit the supported datarates to the .11a
  mandatory rates and use the Minstrel as usual
* Actually restricting the OCB mode to the 5.9 GHz band

Tested with the ath9k card with slightly modified driver.
User-space configuration utilities are not part of this patch.

Rostislav Lisovy (4):
  mac80211: OCB mode + join and leave handling
  mac80211: Use different EDCA config for OCB
  cfg80211: Join and Leave handling for OCB mode
  nl80211: Join and Leave handling for OCB mode
