This current driver does not handle well netpkts used in the write buffers. I learned about this document: https://github.com/apache/nuttx/blob/master/Documentation/components/net/netdriver.rst After I ported and contributed the original driver. However from the document, I understand these types of drivers are simpler to implement and I could simplify the driver and handle correctly the TCP write buffers.
