Description

Interfaces configured as trackv6 for IPv6 get configured with an additional link-local address in the form: fe80::1:1

This was originally to allow access to the firewall from a LAN side client at a known IPv6 address.

However in the years since this was added the expected usage has not materialised and it is now causing problems for some edge cases where it's used as a source address.

This should be removed from trackv6 interface configuration or placed behind a config switch so it can easily be disabled in situations it does cause a problem.

The fe80::1:1 address is not present on any interfaces on 26.03, nor is it in the routing table. Looks good.
