It means 30K was sent off and that you need to call it again with the

So _sftp_write() is different from _channel_write() here? It does not need
to be called again with the same data, when it reports some success - only
when it returns EAGAIN?
None of them should be called again with the same data when success has been
returned and some amount of data has been sent off.
The SCP and SFTP examples are pretty similar in this aspect and show this.
In the SFTP upload case, an application will even work faster if it
"top-fills" the buffer and passes in 200K in the subsequent call again (if
there is more data to send).
