[PATCH proxmox-ve-rs 01/16] frr: add local-as setting

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

This can be used for overriding the ASN for a given neighbor group.
This is particularly useful when running BGP as routing protocol both
for the overlay and the underlay, but utilizing different ASNs for
each.
