Subject: [PATCH v2] wireless-regdb: Update regulatory rules for Brazil (BR)
Date:   Fri,  9 Sep 2022 19:39:47 -0300

The rules for Brazil in wireless-regdb have no comment indicating where
they came from, and haven't been updated in a long time. There have been
some changes to the legislation since then, including the addition of
the 6 GHz and 60 GHz ranges.
