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