That means thos symbols are already present in the kernel.  I'd say that
size of other symbols didn't change between the kernel and the LKM, so you
don't get to see any warning.  But the conclusion is the same: if_ipl is
already compiled in the kernel.

Or, at least, in the /netbsd binary kernel.  Be sure to tell modload to use
the correct binary.
