Its working Ok, But i am facing some problem with the throughput. After a lot of observation , i observed that i am getting un-aligned addresses of the data payload from the TCP/IP stack.because of this problem i always have to do memcpy to a word aligned buffer,because of which throughput is reduced significantly. Does anybody has some solution for this.
