Hi All,

I am working on Xilinx virtex5 ppc44x target. I am seeing that
CONFIG_NET_POLL_CONTROLLER is not present xlltemac_main.c, has anybody come
across it.  And I also see lltemac is working in interrupt driven mode and
not in polled mode. Is it possible support KGDBOE for xilinx LLTEMAC driver
from Xilinx Git:
