Details:

Creating the checksum for UDP/TCP pbufs could be done when copying them (e.g.
in tcp_enqueue() if copy==1), which could significantly increase send
performance.

This would have to be included in pbufs somehow...

And on the receive side, I'm not sure but I think theres not speed gain as
long as it can't be included in the network driver (only if the network
driver does copy using memcpy(), which is slow anyway...)
