That does not sound correct.
The ETag comes with the reply of the last chunk. The client uses it as
an indicator that the upload is finished.
Do you set the header 'OC-Chunked' in all the chunk put requests?

If the oc-mtime header is set, the server reads the modification time
from it and sets it on the target file. This header should be defined.

No, skip the checksum for now. This might become important in the future.
