From bcf4c1ea583cd213f0bafdbeb11d80f83c5f10e6 Mon Sep 17 00:00:00 2001 From: Matan Barak Date: Thu, 11 Jun 2015 16:35:20 +0300 Subject: [PATCH] IB/core: Change provider's API of create_cq to be extendible 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.
