Title: DOCS: Adds description of specific bridged networking interface

The syntax for specific bridged network interfaces has been asked about on the lists, and I know I had the question as well.

I added it to the v1 docs, not the v2 yet - as I don't know how you're going about porting knowledge over to the New Thing.
