wifi: cfg80211: reg: Support P2P operation on DFS channels
FCC-594280 D01 Section B.3 allows peer-to-peer and ad hoc devices to
operate on DFS channels while they operate under the control of a
concurrent DFS master. For example, it is possible to have a P2P GO on a
DFS channel as long as BSS connection is active on the same channel.
Allow such operation by adding additional regulatory flags to indicate
DFS concurrent channels and capable devices. Add the required
relaxations in DFS regulatory checks.
