New Revision: 233421
URL: http://svn.freebsd.org/changeset/base/233421
Log:
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 in
place this actually is redundant. However, the host-PCI-Express bridge
driver is the more appropriate place for implementing this restriction.
