Igor Mac and DP83848 dont read data

Hello all,

I have board with Cyclone III (EP3C25Q240) with DP83848C and design in sopc builderu(igor_mac - clk_0=60MHz, irq=7,...) + quartusu. After this i build my uClinux - Ethernet 10/100Mbit -

- Generic Media Interface ... support

- Opencores (Igor) Emac support

and

- Networ device support - driver for National semic. PHY

after starting it looks ok,

but when i use ping to pc, the data i can see in wireshark, but the data dont read back:

/> ping 192.168.2.200 -c 5

--- 192.168.2.200 ping statistics ---

and statistics after stopping my net sending program looks:

/> ifconfig

Why the ip or nios dont read the data from ethernet line ?

Some idea ?

Thank you very much
