iproute2 question on flushing addresses

I am trying to flush all secondary IPs before flushing primaries, because otherwise it creates a flood of netlink messages as each primary is deleted and a secondary takes over as primary (changing all routes for all other secondaries).

I was thinking this command could work, but it does not appear to do anything:

./local/sbin/ip addr flush dev rddVR17 secondary

While poking at the code..I saw this. It seems to me that the check for IFA_F_SECONDARY is reversed?

int print_addrinfo_primary(const struct sockaddr_nl *who, struct nlmsghdr *n,
void *arg)

{
	struct ifaddrmsg *ifa = NLMSG_DATA(n);

	if (!ifa->ifa_flags & IFA_F_SECONDARY)
		return 0;

	return print_addrinfo(who, n, arg);
}

Thanks,
Ben
