[pve-devel] [PATCH proxmox-ve-rs 07/17] frr: add openfabric types

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

Implement OpenFabric-specific variants of common enums that encapsulate
protocol properties defined in proxmox-network-types. The primary addition
is OpenFabricInterface, which stores protocol-specific timing parameters:
HelloInterval (neighbor discovery frequency), CsnpInterval (database
synchronization frequency), and HelloMultiplier (neighbor failure detection).
Added `is_ipv6` flag to support FRR's command prefixing requirements during
serialization for IPv6-specific commands (we need to add a 'ipv6' prefix
to some commands).
