Thanks , I will check man page and write the below function inside the code if the struct is there under solaries , I have also another issue with gprs directory when compiling as you know ip.h in linux is different than ip.h under solaries , the difference is that solaries has struct ip with different members than linux which has struct iphdr ...I believe we can test GPRS for later stages , can you advise ? I tried to change ip.h to iphdr and change the members inside the code to ip struct members but it didn't work ? Can you advise if we can add the whole iphdr linux struct inside ip.h under solaries ? Does it affect functionality of the program ? Or we need to write the ip communication inside the program gprs_ns_frgre.c from scratch ?
