Author: adrian

New Revision: 227806
URL: http://svn.freebsd.org/changeset/base/227806

Log:
  Use the correct lock when calling msleep().
  
  This fixes panics that users have been seeing when operating in station mode,
  where the interface undergoes a lot more resets then in hostap mode (ie whilst
  doing channel scanning.)
