Author: adrian Date: Sun May 8 07:21:09 2011 New Revision: 221620 URL: http://svn.freebsd.org/changeset/base/221620 Log: Fiddle with the PLL initialisation order to match ath9k/Atheros HAL. This seems to make the AR9160 behave better during heavy scanning, where before it'd hang and require a hard reset to recover.
