application. i am getting below highlighted error while executing server
application.

Hi Ranjith,
Which network device are you binding ? 
DPDK supports over 20 types of nics, listed here:
http://dpdk.org/doc/nics

Do you see your nic (the one that you bind to dpdk, with PCI ID 
0000:02:00.0) in this list ? 

I would guess that this is Marvell NIC (due to 88E8057 in the output of ./dpdk-devbind.py -s). In the list of DPDK supported NICs there is no NIC from Marvell.

Regards,
Rami Rosen
