Interface initialisation for eth0


hi all ..
                 I am working on i386 pc .
I have configure the rtl8139 device driver(of ecos)
.It is working (probably)
but The problem may be  with interface initialisation
.
I am initialising the interface with 
CYGHWR_NET_DRIVER_ETH0_SETUP_OPTIONS
via init_all_network_interfaces()  for 'eth0'
statically.
During startup it is showing all the values  of
addresses  setups for 'eth0'
but when i run the ping test it fails giving the
massage like  host down & recvfrom time out.
             whereas destination host is up & can be
ping from any other pc.When I debug the interface code
I found that the arp request packet has source &
destination IP  address same ,i.e. of target itself .I
am unable to find it out why it is happening .please
help me where is the actual problem ?is it in inteface
initialisation or device driver code ?

Regards!!

umesh ,ensys
