   I do not know if lwip stack is written to fit into the linux kernel
, but I can say it has very thing needed from memory managment to all
oridnary protocols. I know its not so easy to replace linux tcp/ip
stack and there are lot of things to be considered, what I mean to say
is , I just want to say Linux kernel to use lwip for all the data
transfers instead of the normal tcp/ip stack from Linux . Hope you got
my question

  Yes for test run , its not definitely worth to replace the stack
completely with lwip ..I know it ... I don wanna replace it as I said ,
I just want to say the kernel to use lwip for all the data transfers
.... and not the deafult stack

Any ideas , please let me know...????

(But if you *did* replace the kernel's TCP/IP stack, it's likely that
nothing would need to be recompiled. At least, if you did it properly.)
