Well, if the kernel headers can be made namespace clean, we could have
a wrapper <netlink/netlink.h>.  It looks to me like linux/netlink.h is
safe and linux/rtnetlink.h isn't.  We just need an #ifdef __KERNEL__
around all the structures and #defines that are not relevant to user
space.

Does it work if you substitute sys/types.h for asm/types.h?  (It should.)
