Subject: [PATCH 2/2] tools/include: Add rtnetlink.h, id_addr.h and neighbour.h
tools/lib/bpf/netlink.c depends on rtnetlink.h and netlink.h (via
nlattr.h). Older versions of rtnetlink.h and netlink.h can cause
duplicate conflicting definitions to occur, as things like header guards
don't agree. To avoid these mismatches add rtnetlink.h, if_addr.h and
neighbour.h to tools/include with the standard difference check.
