Description

After deleting a ProxyARP virtual IP, the choparp process is still running. To reproduce:

1. Create a new single address ProxyARP virtual IP and apply it. For this example, I created a virtual IP for 192.168.1.150/32.
2. Run ps aux | grep choparp which show the virtual IP is running as expected: root 65423 0.0 0.3 13392 3244 - S 20:28 0:00.00 /usr/local/sbin/choparp -p /var/run/choparp_em0.pid em0 auto 192.168.1.150/32
3. Delete the virtual IP and rerun ps aux | grep choparp. The process for the deleted virtual IP is still running: root 65423 0.0 0.3 13392 3244 - S 20:28 0:00.00 /usr/local/sbin/choparp -p /var/run/choparp_em0.pid em0 auto 192.168.1.150/32

This appears to happen because interface_proxyarp_configure() is called before deleting the virtual IP from configuration, which results in the choparp process being re-spawned.
