OK, bug found in NE2000 driver - function CardSetup().
Original driver doesnt provide a multiplier parameter for address
shifting, and uses a loop to download mac address into NIC
for (i = 0; i < NE2000_LENGTH_OF_ADDRESS; i++)
{
NdisRawWritePortUchar(
Adapter->IoPAddr + (NIC_PHYS_ADDR + i),
Adapter->StationAddress[i]
);
}
My board have IO addresses shifted by 1, So MAC address is written
wrong.
I dont understand why DHCP packets went out correctly, but after this
correction driver starts the work.
I'm going now to apply QFEs ...
