On my TEMAC using Microblaze embedded system. I have a Clock Generator creating a 125 MHz clock that connects
to the xps_ll_temac gtx_clk input. Now If I take a 125 mhz external oscillator clock into the Microblaze system and hook
it to eht GTX_CLK input of the TEMAC and I then open the Clock wizard within the EDK Environment. The new
connection I created will be removed by the Clock Wizard and will replace the connection back to the original
clock 125 mhz signal generated by the clock generator.
Is there a way to get the Clock Wizard to accept the external 125 MHz clock.

I found out that I could add a second clock generator even though the clock wizard will not work for two clock generators.
One of my clock generators runs on a 100 MHz clock to generate 125 MHz and 200 MHz. The other clock generator
is using 33 MHz (on a ML 510 board to generate for the DDR2 and the PLB clock 99 MHz and double rate clocks(198 0 degree and 90 degree) for DDR2.
