From: Leon Romanovsky <leo...@mellanox.com>
The cross-channel feature relies on special primitives to
send and receive work requests.
* WAIT on CQ WR - This WR holds execution of subsequent
requests on that queue until producer index of a CQ is met.
• SEND_EN WR - This WR specifies value of producer index on
the controlled send queue. It enables the execution of all
WQEs up to this producer index.
• RECEIVE_EN WR - Same as SEND_EN but related to a receive
queue.
