Per our realworld discussion, I believe we should add checks for
some conditions (RFC 4862 section 2):
1. ignore tentative addresses
if (ifa->ifa_flags & IFA_F_TENTATIVE)
continue;
2. tests for when the interface's ifa->preferred_lft == 0/deprecatedness:
if (ctinfo == IP_CT_NEW/RELATED && (ifa->ifa_flags & IFA_F_DEPRECATED))
continue;
3. check for invalid addresses
(There might be a flag like tentative..)
if (ifa->valid_lft == 0)
continue;
