ng_protonum: Initial import of protocol number defines

[miri64]

Imports protocol numbers as they are needed for IPv4 and IPv6.

Did you copy the list from somewhere or write it down yourself?

[miri64]

I generated it from the IANA's CSV file with a quick-hacked Python script and adapted the result to my liking (renamed e.g. NG_PROTONUM_IPV6_ICMP to NG_PROTONUM_ICMPV6

@authmillenon: Would you mind to share this script somehow so people might use it to update the list later?

[miri64]

It's not that sophisticated and requires a lot of extra work later on, to achieve the list I created:

import csv
import re

with open("protocol-numbers-1.csv") as csvfile:
    r = csv.DictReader(csvfile, delimiter=",")
    for row in r:
        if (len(row["Keyword"].strip()) == 0):
            continue
        ext = ""
        if row["IPv6 Extension Header"] == "Y":
            ext = "IPV6_EXT_"
        macro = "NG_PROTNUM_" + ext + re.sub("[^A-Z0-9_]", "_", row["Keyword"].upper()).strip("_")
        comment = row["Protocol"]

        if len(comment) == 0:
            comment = row["Keyword"]
        print("#define " + macro + ((32 - len(macro)) * " ") + ("(%3d)" % int(row["Decimal"])) + "   /**< " + comment + " */")

I think for updates it is just best to add the new values by hand. Or does the IANA updates this list in bulk?

[OlegHahm]

To be honest: no clue. But let's see...

[OlegHahm]

ACK

[OlegHahm]

but no beer for this one.
