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...
