- add SPDX header;
- add a document title;
- mark lists as such;
- adjust identation, whitespaces and blank lines;
- add to networking/index.rst.

+====================
+MPLS Sysfs variables
+====================
+
+/proc/sys/net/mpls/* Variables:
+===============================
+
+platform_labels - INTEGER
+       Number of entries in the platform label table.  It is not
+       possible to configure forwarding for label values equal to or
+       greater than the number of platform labels.
+
+       A dense utilization of the entries in the platform label table
+       is possible and expected as the platform labels are locally
+       allocated.
+
+       If the number of platform label table entries is set to 0 no
+       label will be recognized by the kernel and mpls forwarding
+       will be disabled.
+
+       Reducing this value will remove all label routing entries that
+       no longer fit in the table.
+
+       Possible values: 0 - 1048575
+
+       Default: 0
+
+ip_ttl_propagate - BOOL
+       Control whether TTL is propagated from the IPv4/IPv6 header to
+       the MPLS header on imposing labels and propagated from the
+       MPLS header to the IPv4/IPv6 header on popping the last label.
+
+       If disabled, the MPLS transport network will appear as a
+       single hop to transit traffic.
+
+       * 0 - disabled / RFC 3443 [Short] Pipe Model
+       * 1 - enabled / RFC 3443 Uniform Model (default)
+
+default_ttl - INTEGER
+       Default TTL value to use for MPLS packets where it cannot be
+       propagated from an IP header, either because one isn't present
+       or ip_ttl_propagate has been disabled.
+
+       Possible values: 1 - 255
+
+       Default: 255
+
+conf/<interface>/input - BOOL
+       Control whether packets can be input on this interface.
+
+       If disabled, packets will be discarded without further
+       processing.
+
+       * 0 - disabled (default)
+       * not 0 - enabled
