Get rid of this.

And those two variable definitions.

And replace this by:
ccflags-y := -DCONFIG_NETAPP_HWDD -I$(src)/include -I$(src)/include/kernel
Again, I've spent time creating an example that I've tested. Since I
can't reproduce your test case, please try my example, which you can
test as I'm providing the entire source code :)
Best regards,
