    Stop sending gratuitous arp when ip version is 6

    This fix prevents calls to the arping utility for IPv6
    addresses, thereby eliminating errors reported by arping
    for IPv6 addresses.

    The assumption is that NDP, DAD, and RAs are sufficient
    for address resolution and duplicate address detection
    for IPv6, and that unsolicited Neighbor Advertisements (NAs)
    are not required for OpenStack services. If this turns out
    not to be the case for some service/feature, then a separate
    bug should be filed to add support for unsolicited NAs for
    that service.
