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.
