[PATCH proxmox-ve-rs v5 18/46] fabrics: ospf: openfabric: allow user-defined route filter

[Stefan Hanreich <s.hanreich@proxmox.com>]

This property allows overriding the auto-generated filter for fabrics,
which would only install routes from the configured IP prefix into the
kernel routing table. It allows specifying a custom prefix list, that
is used for filtering the routes installed by zebra into the kernel
routing table. It does not affect which routes get announced via OSPF
/ Openfabric.
