The additional 1-cycle in NIC0 is going to be part of the
src_queueing_delay so it is being accounted for.
Does this make sense?
If yes, can you update network delay to
dequeue_time - enqueue_time - 1 ?
And then ship it.
Thanks,
Tushar

But if the stall queue is empty, unstalledMessage is returned false, which
means stalledMessage is true .. which is not quite right.

The extLinkAvail piece of code is not needed. It gets subsumed here.

500,000 seems like a pretty large threshold value in my opinion, whatever
be the size of the network.
It means no packet left the router connected to the NI for 500K cycles.
I think we can make it 50,000.

Hi Lyh,
Garnet requires the ni_flit_size to be same as bandwidth_factor which
means you cannot use different bandwidth factors for different links ..
However, if you specify different link latencies, you can mimic
different bandwidths since flits will take more cycles on some links and
fewer
