    The following macros control which network protocols will be included

    make use of other protocols, therefore it is not always possible to
    remove certain protocols from the build. One example would be UDP. UDP is
    used by DHCP and some other protocols, so if you want to remove UDP you
    must also remove all the protocols that use UDP. You can look at the
    #error macros below to see which protocols are dependant on other
    protocols.
