Some thoughts:

Create RX-RAM that holds <peer IP><peer port><rx seq>
Create TX-RAM that holds <tx seq>
One entity-port per handler (there can be multiple per network port), and a constant for each entity-port to link it to a real port
On RX start:
- Loop through RX-RAM list and check if RxPort=ConfPort and whether the peer IP/port combo exists. Take that if matches or IP field 0.0.0.0 (i.e. empty slot, TBD: maybe we also need a signal to indicate the state of the connection...) as fallback
- If in sequence, process further and prepare TX ACK
- Then forward data to that application port
On TX start (or ACK requested):
- Load TX-RAM to port index, get tx seq.
- TBD: Check that slot is active
- Transmit packet (possibly setting ACK with information, may be done as part of the data package)
- Update tx seq
