[inetstack] Do not print duplicate packet warning when receiving bare acks #1519
Description
Description
We often receive bare acks, especially from a Demikernel remote. These bare acks never bump the sequence number because they are not carrying data. However, we always print a warning saying that we received a duplicate packet.
How to Reproduce
Steps to reproduce the behavior:
- Run this push simulation trace.
- On the last received packet, which is a bare ack, a warning is printed that we've received a duplicate packet.
Expected Behavior
Bare acks are expected so we should not print anything.
