Description of problem:
Once you set 'arp_ip_target'(arp_interval is required meanwhile), you cannot empty it anymore. It means we can't set back 'arp_ip_target' and 'arp_interval' options to default value
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Set a bond with 'arp_ip_target' and 'arp_interval'
2. Try to remove these two options
See the attachment for the details.
Now you have to change 'arp_interval' and 'arp_ip_target' at the same time:
