New Revision: 224242
URL: http://svn.freebsd.org/changeset/base/224242
Log:
This re-enables HT40 channels for use when DFS is enabled.
These should be disabled for the AR5416 in hostap/mesh/ibss mode,
as the AR5416 doesn't have support for radar detection on the
ext channel of a HT40 setup. Later chips do.
