A path extension is a per-entry addition to the forwarding information when packets are sent for that entry over that path.
For example: ip route add 1.1.1.1/32 via 10.10.10.10 out-label 100
The out-going MPLS label value 100 is a path-extension. It is a value sepcific to the entry 1.1.1.1/32 and valid only when packets are sent via 10.10.10.10.

A description of the path that is being extended.
This description is used to match this extension with the [changing] instance of a fib_path_t that is extended

fib_node_index_t fib_path_ext_t_::fpe_path_index |

This is the global index, not the path's position in the path-list.
