your board code which in turn must call smc911x_initialize().  Make sure
that eth_initialize() gets called somewhere in your cpu/board.c call
sequence.  I suspect that while the SMC911x driver is being initialized, it
isn't being registered properly with the networking library.  There are many
examples in the source tree of how to do this.
