I agree that block mode seems dubious. I believe that iSER on iWARP
requires ZBVA though.
You're right.
However, iSER as its spec'd in the IETF, cannot work in Linux due to the
linux networking maintainer's insistence that RDMA connections not share
the same port space. Specifically, the spec mandates (for TCP only, not
IB), that the connection used for the iSCSI login be migrated into rdma
mode. IE you cannot start a different connection for doing the data
moving part...
