Major update to sinic to support VSINIC better
dev/sinic.cc:
- Size the virtualRegs array based on the configured value
- Add debugging stuff for uniquely identifying vnic usage
- Only count totally unprocessed packets when notifying via RxDone
- Add initial virtual address support
- Fix some bugs in accessing packets out of order to make sure that
busy packets are processed first
- Add fifo watermark stuff
- Make number of vnics, zero/delay copy and watermarks parameters
dev/sinic.hh:
add rxUnique and txUnique to uniquely identify tx and rx VNICs
Create a separate list of Busy VNICs since more than one might
be busy and we want to service those first
Add more watermark stuff and new parameters
dev/sinicreg.hh:
Make the number of virtual nics a read-only parameter
add bits for ZeroCopy/DelayCopy
rename Virtual to Vaddr so it's not ambiguous
Add a flag for TxData/RxData to indicate a virtual address
Report rxfifo status in RxDone
python/m5/objects/Ethernet.py:
add more options for the fifo thresholds
add number of vnics as a parameter
add copy type as a parameter
add virtual addressing as a parameter
