First, you also should update before this line. The word 'entry' is a little ambiguous. Here is my proposal.

From:
This is an example to register an entry for port ``ring:0``.

To:
This is an example to register MAC address ``52:54:00:01:00:01``
with resource ID ``ring:0``.

Second, It is too long. It should be less than 80 chars per one line.

I do not understand what is 'the difference' because you do not mention about the another example at first. Do you think 
changing it like this one.

Here is another example in which using keyword ``default`` instead of ``52:54:00:01:00:01``.
``default`` is used for packets which are not matched any of registered MAC addresses.
In this case, all of not matched packets are sent to ``ring:0``.

It is no need anymore.

It is almost similar to the first comment above.

And it is also similar to the second comment above.

Thanks for your contribution.
