68 Updated nwtest to reflect changes in register interface to simple_gmii.
In particular, interrupt bits for packet arrival and sending now need
to be explicitly cleared afterwards.

67 Updated register generator based on testing with simple_gmii. Changed
how interrupt output mux is created, fixed many bugs.
ghutchis 7207d 03h /
66 Modified top level testbench to reflect changes in simple_gmii block ghutchis 7207d 03h /
65 Major restructuring of simple_gmii block.

1) Changed simple_gmii block to simple_gmii_core
2) Migrated RAM instances out of core into top level
3) Removed CPU interface logic and created CPU interface block using
register generator
4) Changed status register to interrupt register and added interrupt
logic
ghutchis 7207d 03h /
64 Created rgen script and expanded available register types ghutchis 7208d 02h /
63 Added simple regression script. -r command runs all tests (serially),
-c command checks results after all tests have completed.
ghutchis 7242d 07h /
62 Reset timeout counter whenever a message is printed ghutchis 7242d 07h /
61 Added timeout disable for large buf sizes ghutchis 7242d 07h /
