New Revision: 204376
URL: http://svn.freebsd.org/changeset/base/204376

Log:
  Disable TSO on BCM5755M controller until I understand better for
  the issue. I still have no idea why TSO does not work on this
  controller. davidch@ also confirmed there is no known TSO related
  issues for this controller.
