[pve-devel] [PATCH proxmox-ve-rs v5 12/22] config: sdn: fabrics: add interface name struct

[Gabriel Goller <g.goller@proxmox.com>]

From: Stefan Hanreich <s.hanreich@proxmox.com>

A simple String wrapper that represents the name of a network
interface. We are restricting the interface name to ASCII-only
characters via the regex, since otherwise the length check would fail,
due to String being Unicode. While network interface names can be
arbitrary bytes and don't correspond to a specific encoding,
restricting it to ASCII seemed sensible here. We can always lift the
restriction later if this is required.
