[PATCH 0/2] wireless-regdb: DFS master changes

[Luis R. Rodriguez]

From: Luis R. Rodriguez <mcgrof@qca.qualcomm.com>

Now that DFS master patches are merged for cfg80211 wireless-regdb
can use being updated with support for exposing the DFS region. This
is a repost with no changes made, just a poke.

Zefir may next want to add a patch for whatever country he's looking to
support with ETSI, for example. TI, may want to do the same :D

  wireless-regdb: Add master DFS region support
  wireless-regdb: add FCC as the DFS region for US

[PATCH 1/2] wireless-regdb: Add master DFS region support

[Luis R. Rodriguez]

From: Luis R. Rodriguez <mcgrof@qca.qualcomm.com>

To support master DFS we add the three known DFS regions which
countries are known to support. 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 when using an old version of CRDA.

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-regd, crda and the 802.11 stack you'll also need proper
DFS support on your device driver.

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.

[PATCH 2/2] wireless-regdb: add FCC as the DFS region for US

[Luis R. Rodriguez]

From: Luis R. Rodriguez <mcgrof@qca.qualcomm.com>

DFS master support in the US requires consideration for DFS
requirements as defined by the FCC rules.
