--000e0cd59906a7c28b04a863e09f Content-Type: text/plain; charset=ISO-8859-1 This patch disables the HT40+DFS check. The later Atheros NICs support radar detection on control and extension channels, and so when the relevant radar detection code is available, the stack should support this functionality. It seems that enforcing this should be a driver/firmware requirement, not a net80211 regulatory requirement. It's only relevant for channels where DFS radar detection is required (which we don't do anyway at the moment!) ; disabling these channels for STA mode seems counterproductive.
