802.11 P DCMA-86P2 Nic displayed successfully

Search all over the internet almost the world only DCMA-86P2 this card can achieve the 802.11p function, but unfortunately, selling this card manufacturers do not provide drivers. After a period of research, I finally found a clue and found that this Nic works in the 802.11a mode by default, even if the driver is modified to make it work in the 802.11p mode, the 802.11a mode is displayed when you use the iwconfig tool. Recently, it finally succeeded in displaying the 802.11p mode (as long as it operates at 5.85 ~ Between 5.925ghz. At present, it has been confirmed by 90% that it really works in the 802.11p mode, because there is no spectrum meter above 5 GHz at hand, so it is not very sure. After a few days of testing, it is now 100% determined that it can work in the 802.11p mode (at least the physical layer ).
