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? Jan Ulvesten |
