New Revision: 323259
URL: https://svnweb.freebsd.org/changeset/base/323259

Log:
  Implement efidp_size
  
  efidp_size will return the size, in bytes, of a EFI device path
  structure. This is a convenience wrapper in the same style as the
  other linux routines. It's implemented by GetDevicePathSize from EDK2
  we already needed for other things.
