====================
docs: Convert alias and bridge to rst

Here is my first attempt at working on converting docs in
Documentation/networking to rst format.  I've picked a couple of trivial
ones to start with.  If there is anything extra I can do to make your
life easier during documentation conversion please say.  (Also if there
is some reason that it would be preferable to _not_ embark on this task
please say :)

This set does not make any changes to the converted files apart from
formatting.

v2:
 - remove incorrect patch from set (changing 'Indices' indentation)
