The following reply was made to PR kern/170904; it has been noted by GNATS. From: dfilter@FreeBSD.ORG (dfilter service) To: bug-followup@FreeBSD.org Cc: Subject: Re: kern/170904: commit references a PR Date: Fri, 24 Aug 2012 01:29:58 +0000 (UTC) Author: adrian Date: Fri Aug 24 01:29:46 2012 New Revision: 239638 URL: http://svn.freebsd.org/changeset/base/239638 Log: Implement an API to fetch the default DFS parameters for the given chip. The only chip this is currently implemented for is the AR5416 HAL family. A follow-up commit will add AR5212 support.
