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 V4:
iser: fixedcompiler warning
isert: back to setting REMOTE_WRITE only for iWARP devices
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.

Sagi Grimberg (1):
mlx4, mlx5, mthca: Expose max_sge_rd correctly
Steve Wise (4):
RDMA/isert: Limit read depth based on the device max_sge_rd capability
RDMA/isert: Set REMOTE_WRITE on DMA MRs to support iWARP devices
RDMA/iser: Limit sg tablesize and max_sectors to device fastreg max depth
ipath,qib: Expose max_sge_rd correctly
