> item
>
> The item is being set according to the attribute value, whether it is
> udp/tcp or ipv4/6.
> Also, there are two condition calls.
>
> If the attribute is neither udp/tcp or ipv4/6 the item is not initialized

> Also, even if the attribute is tcp/udp or ipv4/6, we still have two
> conditions.
>
> This patch changes the conditions, so the item will always be set.
> By doing this, there is also a save in the number of condition calls.
