[Array] IPv6 interface and split-route configuration references

[饕影]

Hello OpenConnect developers,

I am evaluating Array SSL VPN interoperability for a HarmonyOS client
using OpenConnect 9.21. In the released array.c, parse_one_inc_exc
skips IPv6 routes, and parse_interface_info handles
client_ipv4/client_ipv4_mask without filling addr6/netmask6. I have
not found authoritative wire representations for the inner IPv6 client
address/prefix or included/excluded routes.

Is there a known-supported Array AG/vxAG and MotionPro version that
negotiates these fields, or lawful public protocol documentation or a
sanitised configuration example? We need the actual field names/types,
prefix representation and route semantics; guessed fields or manually
injecting IPv6 would not establish compatibility.

Array's November 7, 2023 MotionPro release notes list IPv6 exclusion
and DNS limitations for Windows 1.2.24 and macOS 1.2.20, and I have
asked the vendor about an official evaluation. Clarification of
server/client limitations versus missing OpenConnect parsing would
help identify a useful reference version.

Thank you.
