Follow-up Comment #21, bug #27352 (project lwip):

The problem is that it involves changing from a pointer to a copy everywhere:
OK, we would leave out *one* copy but I don't think that is will be bottle
neck, there are certainly other places that have more impact on performance!

And after that single copy (meaning netconn/socket api), the number of copies
will be the same, no matter if we pass a copy or an u32_t to the raw api
callback.
