There is no iSCSI initiator in SPDK today, so if you're just looking for a
userspace iSCSI initiator that already exists see
https://github.com/sahlberg/libiscsi.
I'm not familiar with this project beyond a cursory glance, but it seems to fit
the bill.

That said, there is both an NVMe-oF initiator and a virtio-scsi initiator in
SPDK already, so an iSCSI initiator would definitely fit into the toolkit. In
order to consider adding one, I think we have to figure out how an SPDK
implementation would be fundamentally better than the already existing
implementations (i.e. libiscsi). If anyone has any insight into that
implementation or any other, and has thoughts on how SPDK could do a faster one,
it would be much appreciated.

Thanks,
