Subject: [PATCH] brcmfmac: add in-driver tables with country codes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This adds early support for changing region. Ideally this data should
be stored in DT as all these mappings are devices specific.

brcmfmac: do not use internal roaming engine by default
Some evidence of curing disconnects with this disabled, so make it a default.
Can be overridden with module parameter roamoff=0
