At this moment Mesh Point is not able to be brought up by userspace such 
as wap_supplicant at VHT data rates because there is no events/NL80211 
defined that userspace can check out if drivers can support Mesh Point 
(802.11s) at VHT data rates or not, hence only HT data rates can be used 
Mesh Point by userspace now.
This patch is introducing NL80211 event to cover the issue.
