This patchset adds cross-channel support.
The cross-channel feature allows to execute WQEs that involve
synchronization of I/O operations’ on different QPs.
This capability enables to program complex flows with a single
function call, hereby significantly reducing overhead associated
with I/O processing.

Modify enum ib_device_cap_flags such that other patches which add new
enum values pass strict checkpatch.pl checks.

The cross-channel feature allows to execute WQEs that involve
synchronization of I/O operations’ on different QPs.
This capability enables to program complex flows with a single
function call, hereby significantly reducing overhead associated
with I/O processing.
Cross-channel operations support is indicated by HCA capability
information.
The queue pairs can be configured to work as a “sync master queue”
or “sync slave queues”.
The added flags are:
1. Device capability flag IB_DEVICE_CROSS_CHANNEL for the
devices that can perform cross-channel operations.
2. CQ property flag IB_CQ_FLAGS_IGNORE_OVERRUN to disable CQ overrun
check. This check is useless in cross-channel scenario.
3. QP property flags to indicate if queues are slave or master:
* IB_QP_CREATE_MANAGED_SEND indicates that posted send work requests
will not be executed immediately and requires enabling.
* IB_QP_CREATE_MANAGED_RECV indicates that posted receive work
requests will not be executed immediately and requires enabling.
* IB_QP_CREATE_CROSS_CHANNEL declares the QP to work in cross-channel
mode. If IB_QP_CREATE_MANAGED_SEND and IB_QP_CREATE_MANAGED_RECV are
not provided, this QP will be sync master queue, else it will be sync
slave.

Add support of cross-channel functionality to mlx5
driver. This includes ability to ignore overrun for CQ
which intended for cross-channel, export device capability and
configure the QP to be sync master/slave queues.
The cross-channel enabled QP supports combination of
three possible properties:
* WQE processing on the receive queue of this QP
* WQE processing on the send queue of this QP
* WQE are supported on the send queue
