The following series implements support for iWARP transports in the iSER
initiator and target. This is based on Doug's k.o/for-4.2 branch.
I've tested this on cxgb4 and mlx4 hardware.
Changes since V1:
Introduce and use transport-independent RDMA core services for allocating
DMA MRs and computing fast register access flags.
Correctly set the device max_sge_rd capability in several rdma device
drivers.
isert: use device capability max_sge_rd for the read sge depth.
isert: change max_sge to max_write_sge in struct isert_conn.
