[Simon Goldschmidt]

Update of task #7236 (project lwip):

                  Status:                    None => In Progress            
        Percent Complete:                      0% => 60%

Follow-up Comment #2:

I just fixed UDP LITE sending, thanks for the input, Frédéric!

- The checksum length was calculated wrong (udp header was missing due to a
mixup of pbufs q and p ;-).

- The partial generation of the checksum made a new function necessary in
inet.c: inet_chksum_pseudo_partial(), it takes an additional argument: u16_t
chksum_len.

Now the question is how we can mix the two inet_chksum_pseudo* functions to
reduce redundant code: can we assume chksum_len can be set to p->tot_len for
the normal inet_chksum_pseudo() or could that produce errors?
