[PATCH V4 0/5] iSER support for iWARP

[Steve Wise <swise@opengridcomputing.com>]

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 V3:

Fixed commit messages based on feedback.

iser: adjust max_sectors

isert: split into 2 patches

isert: always set REMOTE_WRITE for dma mrs

Changes since V2:

The transport independent work is removed from this series and will
be submitted in a subsequent series.  This V3 series now enables iWARP
using existing core services.

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.

      RDMA/iser: Limit sg tablesize and max_sectors to device fastreg max depth
      RDMA/isert: Set REMOTE_WRITE on DMA MRs to support iWARP devices
      RDMA/isert: Limit read depth based on the device max_sge_rd capability
