* The helper functions make Andrew Brown's interface really
* shine. It makes possible to create value on the fly whether
* the sysctl value is read or written.
*
* As shown as an example in the man page, the first step is to
* create a copy of the node to have sysctl_lookup work on it.
*
* Here, we have more work to do than just a copy, since we have
* to create the string. The first step is to collect the actual
* value of the node, which is a convenient pointer to the softc
* of the interface. From there we create the string and use it
* as the value, but only for the *copy* of the node.
*
* Then we let sysctl_lookup do the magic, which consists in
* setting oldp and newp as required by the operation. When the
* value is read, that means that the string will be copied to
* the user, and when it is written, the new value will be copied
* over in the addr array.
*
* If newp is NULL, the user was reading the value, so we don't
* have anything else to do. If a new value was written, we
* have to check it.
*
* If it is incorrect, we can return an error and leave 'node' as
* it is: since it is a copy of the actual node, the change will
* be forgotten.
*
* Upon a correct input, we commit the change to the ifnet
* structure of our interface.
