Recently I had to drive smsc9115 in our develop board, it is a bootloader based non-pci NIC driver. It can only use poll because the bootloader can't support interrupt. I refered SRC-118-LINUX-SIMPLE code in smsc website, it adopt interrupt method.
Now the 9115 can normally send ping packet to the PC NIC card, but it can't receive the reply packet from PC. The PC NIC card ping 9115 and 9115 can receive ping packet, but the received data is longer than the sent.Why?
What padding value should be of readfifo function? Now I use(dwPacketLength+2+3)>>2.

I decided to post my question in this forum, but I don't know how to delete
the duplicate thread in other place.
Please do not close it , I do need help.
Thank you!
Now the most confused problem is that smsc9115 always received more data than the sent data.
Because the packet length is got from register RX_STATUS_FIFO, I wonder why the incoming RX_STATUS_FIFO value is wrong?
The other strange problem is that smsc9115 can't receive icmp message , but it can receive udp and arp message. I am not sure it's connected with addres filtering, should I open promiscuous mode?
