Alexander A. Klimov 535094a0c9 Replace HTTP links with HTTPS ones: X.25 network layer
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
          If both the HTTP and HTTPS versions
          return 200 OK and serve the same content:
            Replace HTTP with HTTPS.

CCITT X.25 Packet Layer

config X25 tristate "CCITT X.25 Packet Layer" help X.25 is a set of standardized network protocols, similar in scope to frame relay; the one physical line from your box to the X.25 network entry point can carry several logical point-to-point connections (called "virtual circuits") to other computers connected to the X.25 network. Governments, banks, and other organizations tend to use it to connect to each other or to form Wide Area Networks (WANs). Many countries have public X.25 networks. X.25 consists of two protocols: the higher level Packet Layer Protocol (PLP) (say Y here if you want that) and the lower level data link layer protocol LAPB (say Y to "LAPB Data Link Driver" below if you want that).

  You can read more about X.25 at <https://www.sangoma.com/tutorials/x25/> and
  <http://docwiki.cisco.com/wiki/X.25>.
  Information about X.25 for Linux is contained in the files
  <file:Documentation/networking/x25.rst> and
  <file:Documentation/networking/x25-iface.rst>.

  One connects to an X.25 network either with a dedicated network card
  using the X.21 protocol (not yet supported by Linux) or one can do
  X.25 over a standard telephone line using an ordinary modem (say Y
  to "X.25 async driver" below) or over Ethernet using an ordinary
  Ethernet card and the LAPB over Ethernet (say Y to "LAPB Data Link
  Driver" and "LAPB over Ethernet driver" below).

  To compile this driver as a module, choose M here: the module
  will be called x25. If unsure, say N.
