nvme-fabrics: Add target support for FC transport (c5343203) · Commits · 戴 / test

Implements the FC-NVME T11 definition of how nvme fabric capsules are performed on an FC fabric. Utilizes a lower-layer API to FC host adapters to send/receive FC-4 LS operations and perform the FCP transactions necessary to perform and FCP IO request for NVME. The T11 definitions for FC-4 Link Services are implemented which create NVMeOF connections. Implements the hooks with nvmet layer to pass NVME commands to it for processing and posting of data/response base to the host via the different connections. Signed-off-by:
