     17 * Important comment:
     18 * IFA_ADDRESS is prefix address, rather than local interface address.
     19 * It makes no difference for normally configured broadcast interfaces,
     20 * but for point-to-point IFA_ADDRESS is DESTINATION address,
     21 * local address is supplied in IFA_LOCAL attribute.
     22 *
     23 * IFA_FLAGS is a u32 attribute that extends the u8 field ifa_flags.
     24 * If present, the value from struct ifaddrmsg will be ignored.
