New Revision: 266541
URL: http://svnweb.freebsd.org/changeset/base/266541

Log:
  - Fix a bug where the TLBPC value was forced to being odd for IN
  direction isochronous transfers.
  - Remove setting of fields which does not belong to the respective
  TRBs. These fields are currently set as zero and this is more a
  cosmetic change.
