In order to modify the regulatory database schema in a backward compatible way we use one of the two pad bytes which were unused. By using one of the two pad bytes we end up keeping new regulatory databases with DFS region support compatible with older verions of CRDA, the DFS region would just not be sent to the kernel. DFS master is only required for modes of operation which iniate radiation on DFS channels, we will start supporting DFS with AP mode of operation. Without DFS master support you cannot intiate radiation on those channels (AP, Mesh, IBSS, P2P). Apart from support from wireless-regdb, crda and the 802.11 stack you'll also need proper DFS support on your device driver to use this. A country can only map to one DFS region at a time for all frequency regions. After this patch countries can start being mapped to their own DFS region. Signed-off-by: Luis R.
