the temac driver and Makefile are copied to drivers/net/xilinx_gige. This
xilinx_gige directory is not available in the MVL 3.1 Preview Kit, only in the full
Professional kit. We put the temac driver here mostly to take advantage
of the JUMBO_FRAME_SUPPORT in kernel configuration.<o:p></o:p></span></font></p>

drivers/net/xilinx_enet directory for the temac driver and just enable the Xilinx

adapter.c in the driver to define the CONFIG_XILINX_GIGE_JUMBO constant.<o:p></o:p></span></font></p>
