From f3da6577da67a3cd44610ca54e308c6838c92157 Mon Sep 17 00:00:00 2001 From: Leon Romanovsky Date: Wed, 28 Nov 2018 20:53:41 +0200 Subject: [PATCH] RDMA/mlx5: Initialize SRQ tables on mlx5_ib Transfer initialization and cleanup from mlx5_priv struct of mlx5_core_dev to be part of mlx5_ib_dev. This completes removal of SRQ from mlx5_core.
