There are 2 LWIP EDK example designs, one of which is supposed to support the hard Gigabit temac core on the Virtex 4 FX series. In fact, both zip files are identical and for the 10/100 soft core. Has anybody found the Temac example, or heard from Xilinx whether the Temac example will be out with the next EDK service pack (due about now)?
