It'll use tools/include copy of linux/in.h to generate a table to be
used by tools, initially by the 'socket' and 'socketpair' beautifiers in
'perf trace', but that could also be used to translate from a string
constant to the integer value to be used in a eBPF or tracefs tracepoint
filter.
When used without any args it produces:
$ tools/perf/trace/beauty/socket_ipproto.sh
static const char *socket_ipproto[] = {
[0] = "IP",
[103] = "PIM",
[108] = "COMP",
[12] = "PUP",
[132] = "SCTP",
[136] = "UDPLITE",
[137] = "MPLS",
[17] = "UDP",
[1] = "ICMP",
[22] = "IDP",
[255] = "RAW",
[29] = "TP",
[2] = "IGMP",
[33] = "DCCP",
[41] = "IPV6",
[46] = "RSVP",
[47] = "GRE",
[4] = "IPIP",
[50] = "ESP",
[51] = "AH",
[6] = "TCP",
[8] = "EGP",
[92] = "MTP",
[94] = "BEETPH",
[98] = "ENCAP",
};

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
