Compile time error, compiling Xilinx Linux 2.6 for XPS LLTEMAC

Ah, thanks mike... you knocked the answer loose out of my brain...
In EDK 9.2., the ll_temac generates either SDMA or FIFO defines, as necessary.
The platform data structure contains entries for both, with the correct ones being ignored. In order to get the code to compile, there are some defines in xparameters.h which have:
#define XPAR_LLTEMAC_0_LLINK_CONNECTED_FIFO_INTR 0xdeadbeef
#define XPAR_LLTEMAC_0_LLINK_CONNECTED_DMATX_INTR 0xdeadbeef
#define XPAR_LLTEMAC_0_LLINK_CONNECTED_DMARX_INTR 0xdeadbeef
after including xparameter_ml403.h
I'm guessing maybe you overwrote the xparameters.h file and got rid of these redefines? You can define it to be whatever you want, since the value will be ignored if you are using SDMA.
In EDK 10.1, the BSP generator will always generate all the defines (even ones which are not sensible in the current configuration), which avoids the above annoyances.

That interrupt is defined if you build a xps_ll_temac with the
xps_ll_fifo interface. Since you already stated that you're using the
mpmc, I'm going to assume that you have it connected to a SDMA
controller on the mpmc. As such the driver should be looking for that
definition, and not the FIFO interrupt. I don't have your version of the
virtex_devices.c to have a reference as to how the platform device is
being defined, so hopefully either Stephen N can chime in w/ more
information, or point me to the version of the virtex_devices.c that
you're using and I can try to provide some more assistance.

that should be a small problem, and i think that its solution should be
I generate a base system using EDK 9.2.02 , the base system contains
XPS_LL_TEMAC , MPMC and other components,
I generate the software libraries and copy xparameters file into proper
kernel folder. I configure that kernel and add kernel support for
while doing make I encounter this error:
'XPAR_LLTEMAC_0_LLINK_CONNECTED_FIFO_INTR' undeclared here (not in a
I think that this definition should be available in xparameters_ml403.h
file but i see that there is no such definition.
I added a dummy definition for myself there to complete kernel
compilation, don't know the correct value for it of course.
