network driver macvlan does not receive an ipv6 address from dhcp

[TrevorBenson]

Issue Description

Creating podman network using driver macvlan with ipv6 enabled and ipam-driver dhcp passes through an ipv4 address, but not an ipv6 address.

Steps to reproduce the issue

Steps to reproduce the issue
1.podman network create -d macvlan -o parent=enp1s0 --ipv6 --ipam-driver=dhcp macvlan-dhcp
2. systemctl enable --now netavark-dhcp-proxy.socket
3. podman run -dit --name alpine_macvlantest --hostname apline1 --network macvlan-dhcp alpine
4. podman exec -it alpine_macvlantest ip a s
5. Observe no IPv6 address assigned via dhcp request:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eth0@eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP qlen 1000
    link/ether 4a:cf:e9:f8:b7:9c brd ff:ff:ff:ff:ff:ff
    inet 192.168.197.63/24 brd 192.168.197.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::48cf:e9ff:fef8:b79c/64 scope link 
       valid_lft forever preferred_lft forever

Creating a connection profile via nmcli for type macvlan using the same macvlan.parent enp1s0 with ipv4 and ipv6 set to auto the DHCP request produces both an IPv4 and an IPv6 address assigned from DHCP.

Describe the results you received

Only an IPv4 address is assigned.

Describe the results you expected

An IPv6 address is also assigned.

ipv6 support in the netavark dhcp proxy is not implemented so this is expected for now
