Author: jhb Date: Wed Dec 2 16:26:18 2009 New Revision: 200037 URL: http://svn.freebsd.org/changeset/base/200037 Log: ndis_scan_results() can sleep if the scan results are not ready when ndis_scan() is called. However, ndis_scan() is invoked from softclock() and cannot sleep. Move ndis_scan_results() to the ndis' driver's scan_end hook instead.
