I expect users that need to use this struct to also need to include the
header that defines it, right?

rtnetlink.7 tells #include <linux/rtnetlink.h> is needed in SYNOPSIS
and the header internally includes <linux/if_addr.h>, so users need
not include it explicitly for struct ifa_cacheinfo.

We should probably specify it by using
an #include.  What do you think?

So I think we need not mention linux/if_addr.h here.
