pfSense configures fe80::1:1 on lan interface without track6
100%
Description
While creating CARP IPv6 VIP interface on clean pfSense CE 2.4.5-p1 install,
I noticed that both nodes have fe80::1:1 address:
# ifconfig vtnet0
vtnet0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=80028<VLAN_MTU,JUMBO_MTU,LINKSTATE>
ether 0c:c5:49:d7:8c:00
hwaddr 0c:c5:49:d7:8c:00
inet6 fe80::1:1%vtnet0 prefixlen 64 scopeid 0x1
inet6 fc00:3::51 prefixlen 64
inet6 fc00:3::55 prefixlen 64 vhid 2
inet 192.168.3.51 netmask 0xffffff00 broadcast 192.168.3.255
inet 192.168.3.55 netmask 0xffffff00 broadcast 192.168.3.255 vhid 1
nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
media: Ethernet 10Gbase-T <full-duplex>
status: active
carp: MASTER vhid 1 advbase 1 advskew 0
carp: MASTER vhid 2 advbase 1 advskew 0
and secondary node:
# ifconfig vtnet0
vtnet0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=80028<VLAN_MTU,JUMBO_MTU,LINKSTATE>

both nodes have static IPv6 addresses, and no any other IPv6 addresses - WAN is DHCP (IPv4), and SYNC interface is Static IPv4
I don't this is a CARP/HA issue, it seems to be a bug with link_interface_to_track6() or interface_track6_configure() and clean config

Found the issue -
on initial interface setup in console, it automatically set
DHCP + DHCP6 on the WAN interface, and 192.168.1.1 + Track WAN interface on the LAN interface,
but when I go to the Interfaces / LAN page, it shows IPv6 Configuration Type = None,
because of ipaddrv6 is empty:
<lan>
<enable></enable>
<if>vtnet0</if>
<ipaddr>192.168.1.1</ipaddr>
<subnet>24</subnet>
<ipaddrv6></ipaddrv6>
<subnetv6></subnetv6>
<media></media>
<mediaopt></mediaopt>
<track6-interface>wan</track6-interface>
<track6-prefix-id>0</track6-prefix-id>
<gateway></gateway>
<gatewayv6></gatewayv6>
</lan>
after switching IPv6 mode to Static, fe80::1:1 is not removed from the interface

Remove fe80::1:1 alias from interface in interface_configure() "remove all IPv4 and IPv6 addresses" loop:

None, this is correct, it empty after setting IPv6 to none in 'Set interface(s) IP address' menu

works fine on 2.5.0.a.20200622.1850 - fe80::1:1 successfully removed from interface after switching from Track Interface to other IPv6 Configuration Type
