Some inconsistencies
Hi there,

 

I found some issues that I did not follow:

1.      Throughput in PPS and Gbps don't seem to match. For example, I do not understand how 2.2e6 fps translates to 7Gbps for large frames (it should be around 26Gbps).

2.      Even for small packets, the latencies are in us. Shouldn't they be in ns? The authors claim 20us is in line with ASIC based switches (which I don't think it is. Most hardware switches take a few ns to switch packets. For example, Trident-1 took around 600ns for L3 forwarding and 400ns for L2 forwarding. This was way back in 2009).

3. Adding more MAC addresses must simply increase the memory size. Given that all of these are exact-match tables, I fail to understand
