CARP VIPs are configured on disabled interfaces at boot time

Description

When a CARP VIP is configured for a disabled interface, it is still configured by pfSense during the boot process even though the main interface address is not present. This leads to the interface being active when it should not be.

CARP VIPs for disabled interfaces should be skipped.

An interface can show as "up" as long as it has a link. A VLAN will exist at the OS level if a tag is defined. The difference between enabled and disabled would be whether or not it has an IP address configured and if it's being put to use, more or less. Can you provide more detail about what, specifically, it is that you're seeing?

Did little more testing.

It seems that if there is an carp address assigned to interface the interface will come up after reboot even if it is not enabled.

With carp address disable does not survive reboot.

1. staring condition: lagg1_vlan9 with carp address
2. disable interface -> lagg1_vlan9 is deleted from system (ifconfig: interface lagg9_vlan9 does not exist)
3. reboot -> interface setting on web gui shows interface not enabled. ifconfig shows interface up with ip addresses.

Without carp address things are fine.

1. starting condition: lagg_vlan9
2. disable interface -> lagg1_vlan9 is deleted from system (ifconfig: interface lagg9_vlan9 does not exist)
3. reboot -> interface settin on web bui shows interface not enabled. ifconfig show interface up with no ip addresses.
