Example:
wlan0:T10/10,R(10+20)/31 TCP:T0,R0,D0 UDP:T0,R10,D0 ICMP:T0,R0,D0 ICMP6:T0,R0,D0

below command to create mbim NIC on host

NuttX's MBIM device implementation adds an additional MBIM network
card to the NuttX system, which can debug the data communication with
the host, but this network card is unnecessary and needs to be removed
when the business actually uses this driver, And the cdcncm_receive
method needs to be re-implemented.

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

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.
