NLMSG_SPACE(len) is a Macro to return the required buffer space
to carry a netlink message payload of given length. With the
maximum payload length you get the maximum required buffer space.

This is 1024 byte (as before) plus netlink message header size
plus header padding space ... usually less than 4096 byte ...
that is you do not waste unnecessary buffer space.
