Author: bschmidt Date: Sun May 8 11:01:53 2011 New Revision: 221640 URL: http://svn.freebsd.org/changeset/base/221640 Log: Disable background scan support for 4965 adapters. On legacy channels every once in a while the firmware throws a SYSASSERT on line 208. On HT channels though this does always happen and I'm not aware of any workaround currently.
