Refactored the fpga and testbench so the RVVI can be synthesized cleanly and simulated without any major code changes.
...
Adds three new configuration parameters to control enabling the RVVI packetizer and how much latency should exist between packets and the initial startup delay.

Really close to having the trigger in module work.
...
Can trigger on the data of the correct frame, but trigger in is still not
working.

Added some debug code to count frames sent to the ethernet mac and frames sent to the phy.
...
Removed the external reset of the phy and now it always reliably starts in the same way. The first 0x117 frames are always captured.
