Rework the Ameba WHC WiFi driver from the legacy flat net_driver_s model to the netdev lower-half framework (netdev_lowerhalf_s + netdev_ops_s with .transmit/.receive, IOB-based quota backpressure and a dedicated NETDEV_RX_THREAD). This provides real TX backpressure and moves RX off the IPC callback onto a bounded rx queue. Raise the host TX skb pool (skb_num_ap) to a minimum of 16. The SDK default of 4 is too small for sustained TCP TX: the host send runs out of buffers (-2), which exhausts retransmits and tears the connection down. Enable CONFIG_NET_TCP_SELECTIVE_ACK (which selects OUT_OF_ORDER) in both board defconfigs. WiFi's occasional loss otherwise stalls TCP RX on RTO timeouts (~2 Mbit/s); with SACK + out-of-order queuing RX recovers to ~12-13 Mbit/s. Signed-off-by: raul_chen <raul_chen@realsil.com.cn> |
