Static IP address (IPV6) is not being assigned to container. Keeps getting taken by another container

[Ttfgggf]

Issue Description

Describe your issue

It is simlar to two github issues raised in the past regarding Static IP addresses not be respected and their being an IPAM error.

(#15708)

(#21194)

Steps to reproduce the issue

Steps to reproduce the issue

1. Set MAC Address for containers using PodmanArgs=--mac-address 12:34:56:78:9a:da in a Quadlet File.
2. Set IP6 within quadlet file for container
3. After a restart, a container errors and the message is "Error: IPAM error: requested ip address is already allocated to container ID

Describe the results you received

Describe the results you received

Containers for some reason aren't setting the IPv6 address statically.

Describe the results you expected

Describe the results you expected

To set IPv6 address statically for containers and not to deviate from what I have set it as.

Please provide a proper reproducer, how is the network and the container created?

Please provide a proper reproducer, how is the network and the container created?

So the network that is created is a MacVLAN based using the macvlan driver
Running with the IPAM driver of host-local.
IP range is allocated from the private IPv4 addresses and GUA's for IPv6.
.network file specifies a parent interface which is linked to the NIC on the host system.

Each container is assigned an IPv4 and IPv6 address using IP and IP6 directives within each container quadlet file.
Some containers are assigned a MAC address using PodmanArgs (as mentioned above already).
