Is this being compiled on a non-ppc/powerpc platform? That might explain it. UCC_GETH is
defined in drivers/net/Kconfig, but UCC_FAST is defined in
arch/powerpc/sysdev/qe_lib/Kconfig. So I supposed if you don't compile for ARCH=powerpc,
then arch/powerpc/sysdev/qe_lib/Kconfig is never loaded?
If that's the case, then we're always going to have this problem with platform-dependent
drivers in the /drivers/ directory. The ucc_geth driver depends on the "QE library",
which is present only on some PowerPC processors, so we put the config options for the QE
in arch/powerpc. But since ucc_geth is a standard Ethernet driver, it exists in drivers/net.
