Author: adrian Date: Wed Jul 20 05:59:28 2011 New Revision: 224224 URL: http://svn.freebsd.org/changeset/base/224224 Log: This patch removes a check in ifconfig which disables HT/40 channels on frequency bands with DFS. All Atheros chipsets >= AR9001 support radar event detection on HT40 extension channels. This should be a chipset specific item rather than enforced in the regulatory domain database. In addition, it's irrelevant for STA mode, as the radar detection is done by the access point, not the STA.
