If you have a look to the 16.10.3 tag on Github, the Bridge feature is not there yet:
It is present only on the master branch, which gives you a preview of the latest developments in the framework, but which will only be usable:
- either by waiting for the next official product release for your hardware
- or by rebuilding the framework yourself from Github
Packages for DS or legato-spm are tight to the hardware releases, that's why there are no package yet including the current Github master code.
