First, I'll submit iSER patches that enable iWARP in the same manner that NFSRDMA does. Namely, have iSER look at the transport type and set the MR access flags accordingly. That is a very simple set of changes. I submitted this as the first series earlier in the week. The main comment was to fix the rdma drivers to set max_sge_rd and use that to adjust the read sge depth. Next, I'll submit the transport independent core changes to remove the ULPS from having to know about transport access_flag differences. Included in this series will be changes to iSER and NFSRDMA to make use of the new services.
