3c4897310b tcp_input: if tcp->req > recvreq, send ack only when state is TCP_ESTABLISHED 
The Bluetooth network on N62 does not retransmit packet, so no packet
retransmition if we drop one, we will drop packet when tcp_close_eventhandler
is register and invoke by tcp_input. then we will always early return and
never stop, the peer will only close the connection if we send reset packet.

precondition:
close -> register tcp_close_eventhandler;

tcp_input -> tcp_callback(TCP_NEWDATA) -> devif_conn_event -> tcp_close_eventhandler
-> flags &= ~TCP_NEWDATA -> NOT entry tcp_data_event -> conn->recvreq NOT increase

old flow:
tcp_input -> tcp->seqno greater than conn->rcvseq -> tcp_send(TCP_ACK)

with this patch:
tcp_input -> tcp->seqno greater than conn->rcvseq -> !TCP_ESTABLISHED
-> case TCP_FIN_WAIT_1 -> dev->d_len greater than 0 -> tcp_reset

0bad215cf8 net/tcp: fix tcp will not close when tcp retransmission reaches TCP_MAXRTX 
In "psock_send_eventhandler",when retransmit count bigger TCP_MAXRTX nuttx will set release wrb. But before this it will also set "conn->tx_unacked = 0" if we only retransmit one packet(conn->tx_unacked == sent),and In func "tcp_timer" only "conn->tx_unacked > 0" will close the tcp conn. So app will never close if nuttx retransmit over max timers.

41ab3a9cfe net/udp_input: Only dup packets for broadcast / multicast. 
We found previous multicast support (https://github.com/apache/nuttx/pull/12015) harms some unicast situation, and the `udp_input` should not dup packets for unicast.
Now, we only pass broadcast / multicast packets into each listener and let the code under control of `CONFIG_NET_BROADCAST`.
