Update of bug #49292 (project lwip):

                  Status:                    None => Invalid                
             Open/Closed:                    Open => Closed                 


Follow-up Comment #1:

Your port does not seem to correctly implement struct packing. Triple check
this - sizeof(struct ip_hdr) MUST BE 20 - you won't get far without this
working correctly.

See https://en.wikipedia.org/wiki/IPv4#Header
-> header (without options) is 20 bytes
