iSER in Opensolaris

Yet another interesting putback to Opensolaris: PSARC 2008/395 iSER: iSCSI Extensions for RDMA. With this extension it´s for example possible to do iSCSI over Infiniband circumventing the complete TCP/IP stack and just copy the data directly from memory to memory via Remote DMA without involving OS infracstructure for this task. The ARC case is in redacted-mode at the moment, so the arclog for this case isn´t really useful at the moment.
