In 1st configuration i considered MEM_SIZE is used for both TCP_WND(2k) &
TCP_SND_BUF(6k) 
and in 2nd only for TCP_SND_BUF(6k).

How to decide the PBUF_POOL_BUFSIZE? Actually i m not understanding it
completely.

As i have configured TCP_WND = 2k & TCP_SND_BUF is 6k so i kept it 40.

My doubt is, does MEM_SIZE use for only TCP_SND_BUF or for both (TCP_WND &
TCP_SND_BUF)?
