nvmet-tcp: add NVMe over TCP target driver (872d26a3) · Commits · 戴 / test

This patch implements the TCP transport driver for the NVMe over Fabrics target stack. This allows exporting NVMe over Fabrics functionality over good old TCP/IP. The driver implements the TP 8000 of how nvme over fabrics capsules and data are encapsulated in nvme-tcp pdus and exchaged on top of a TCP byte stream. nvme-tcp header and data digest are supported as well.
