New Revision: 328194
URL: https://svnweb.freebsd.org/changeset/base/328194

Log:
  Add sysctls to control device side USB identifiers. This makes it
  possible to change string and numeric vendor and product identifiers,
  as well as anything else there might be to change for a particular
  device side template, eg the MAC address.
