    Format the protocol number to be passed to pyroute2

    When a new IP route is created, before passing the route protocol,
    find if it is a string and if this string is on the pyroute2 defined
    protocols. In this case, pass the protocol number.

    In the same way, when the IP route is returned, if the protocol is a
    number, convert it to the corresponding protocol string.
