Evgeny 7f5325ac24 etcp_router: fix inflight underflow by splitting rx_acked into tx_acked + last_sent_ack_seq ... rx_acked was used for two conflicting purposes: 1. remote ack of our sends (inflight = tx_seq - rx_acked) 2. our last sent ACK seq (dedup: rx_seq != rx_acked) When the ack timer fired and set rx_acked = rx_seq, it overwrote the inflight-tracking value. If rx_seq > tx_seq, the computation tx_seq - rx_acked underflowed (e.g. 18 - 24 = 0xFFFFFFFA), permanently blocking router_drain_send_q and causing send_q to grow indefinitely. Fix: - Split rx_acked into tx_acked (remote ack, for inflight) and last_sent_ack_seq (our ACK, for dedup) - Incoming ACK handler only advances tx_acked forward (stale guard) - Use int32_t cast on all inflight comparisons to handle stale states - Add etcp_router architecture diagram (doc/etcp_router_arch.md)		4 months ago
