URL: https://github.com/apache/nuttx/pull/19423
## Summary
Tunes the TCP stack and driver resources for the Realtek Ameba WHC Wi-Fi data
path (NuttX runs on the application core; the Wi-Fi MAC runs on a companion
core reached over an on-chip IPC) on both `rtl8720f_evb` and `pke8721daf`,
plus an open-network association fix and a documentation note.
- **TCP tuning (both boards):** cap the advertised receive window
(`NET_RECV_BUFSIZE`) to about the out-of-order reassembly capacity and
bound
in-flight TX (`NET_SEND_BUFSIZE`); keep out-of-order reassembly but disable
selective ACK. #19353 enabled `NET_TCP_SELECTIVE_ACK` on both boards; on
the
lossy Wi-Fi TX path the sender-side selective-ACK recovery does not
reliably
repair multi-segment holes and stalls TX, so NewReno (out-of-order only) is
used instead — same steady-state throughput, robust recovery. Also drops a
dead busy-wait in the transmit path and right-sizes the host TX skb pool.
- **Open-network fix:** clear the stored passphrase on explicit disconnect so
a later open-AP connect is not mis-driven as WPA2 by a stale psk; set
`key_id = -1` for non-WEP.
- **Docs:** add a "Performance tuning" section to the network driver guide
(RX quota backpressure, RX thread priority vs. the companion-core delivery
task, window / IOB pool sizing).
## Impact
Wi-Fi TCP/UDP throughput and stability on the two Ameba boards. No public API
change. Reverses the `NET_TCP_SELECTIVE_ACK` enablement from #19353 while
keeping `NET_TCP_OUT_OF_ORDER`.
## Testing
`iperf` against a windows host, `nsh` configuration, both boards:
