>Hmm, I wonder why only NVMe-FC? Or is this just for the moment? We also
have the FC transport class for SCSI; I assume this could feed the same
IDs into the LLDs.
At present it supports only for SCSI-FC .
In future we are adding the support for NVMe-FC
But to make it generic and avoid duplication we added this under
/sys/class/fc .

Ewan was mentioning that at some point there is a plan  to decouple the FC
transport
somewhat so that there is a layer that represents the FC stuff regardless
of the FC4 type
(SCSI, NVMe). When we have this layer we can move the things accordingly.

Regards,
Muneendra.
