[lwip-users] Don't fragment flag

check out ip.c:   IPH_OFFSET_SET(iphdr, htons(IP_DF));


Can’t be correct, can it ?


During a test which I carried out where the underlying network had a TCP MSS (=512) less than my board; I went into trouble due to this flag. I changed it to

IPH_OFFSET_SET(iphdr, 0); and everything worked fine.



The flag tells the underlying network to don’t fragment the IP packet? Why making such a requirement?
