Subject: [PATCH for-next V2 1/9] IB/core: Change provider's API of create_cq to be extendible
From: Or Gerlitz <ogerlitz () mellanox ! com>
Date: 2015-05-31 12:14:09
Message-ID: 1433074457-26437-2-git-send-email-ogerlitz () mellanox ! com
[Download RAW message or body]
From: Matan Barak <matanb@mellanox.com>
Add a new ib_cq_init_attr structure which contains the
previous cqe (minimum number of CQ entries) and comp_vector
(completion vector) in addition to a new flags field.
All vendors' create_cq callbacks are changed in order
to work with the new API.
This commit does not change any functionality.
