as you suggested for the Kevin i tried creating the new package for
DP83816. and one .cdl and one .inl for making it support for the
Still i am not able to initialize the network properly. i am facing
the following problem
1. after starting the redboot it will go and initialize all the NIC's
2. while initializing our NIC it is not finding the base address of the
NIC so it is returning with no device found.
in the code i found the place where it is failing.
that is in if_dp83816.c
if (!base) return false; // No device found
4. for other microcontrollers like i82559 this base address is assigned as
p_i82559->io_address = dev_info.base_map;
here io_address is the base adderss.
3. my doubght is how we are managing this problem in the PPC version

You need to create a new package to customize the generic DP83816
driver to the hardware. Take the MOAB package, copy it, rename it, and
adapt it to the PC. Since it is a PCI device, you probably dont need
to do very much. Now add that package to the configuration.
