The max depth of a fastreg mr depends on whether the device supports
DSGL or not. So compute it dynamically based on the device support and
the module use_dsgl option.

Some HW platforms can reorder read operations, so we must rmb() after
we see a valid gen bit in a CQE but before we read any other fields from
the CQE.

1) timedout endpoint processing can be starved. If there is continual
CPL messages flowing into the driver, the endpoint timeout processing

iw_cxgb4.
The patches series is created against 'infiniband' tree, 'for-next' branch.
And includes patches on iw_cxgb4 driver.

There is a race when moving a QP from RTS->CLOSING where a SQ work
request could be posted after the FW receives the RDMA_RI/FINI WR.
The SQ work request will never get processed, and should be completed
with FLUSHED status. Function c4iw_flush_sq(), however was dropping

If kmalloc() fails in c4iw_alloc_ucontext(), the function
leaves but does not set an error code in ret variable:
it will return 0 to the caller.
This patch set ret to -ENOMEM in such case.

The code that resolves the passive side source mac within the rdma_cm
connection request handler was both redundant and buggy, remove it.
It was redundant since later, when an RC QP is modified to RTR state
the resolution will take place in the ib_core module. It was buggy b/c
