Details:

Hello
Using ftp to list my files directory, I got some problem with the number of
item I can send.
I'm using the toelke/lwip-ftpd
During the send_next_directory, I expected to call the tcp_output function to
overcome this limitation, but the function does not allow to send data during
the tcp_input phase.
So it requires to store all data in a buffer (which can become huge) before
sending them.
Why not allowing to send data with a specific flag ?
In this specific case the sending is very limited....
Best Regards
