Author: marius Date: Sat Mar 31 00:13:46 2012 New Revision: 233724 URL: http://svn.freebsd.org/changeset/base/233724 Log: MFC: r233421 Given that this is a host-PCI-Express bridge driver, create the parent DMA tag with a 4 GB boundary as required by PCI-Express. With r232403 (MFC'ed to stable/8 in r233394) in place this actually is redundant. However, the host-PCI-Express bridge driver is the more appropriate place for implementing this restriction.
