From 52c368dc3da7beb7b283133024af1b6d07bf93b9 Mon Sep 17 00:00:00 2001 From: Saeed Mahameed Date: Fri, 29 Mar 2019 15:37:55 -0700 Subject: [PATCH] net/mlx5: Move health and page alloc init to mdev_init Software structure initialization should be in mdev_init stage. This provides a better logical separation of mlx5 core device initialization flow and will help to seamlessly support creating different mlx5 device types such as PF, VF and SF mlx5 sub-function virtual device. This patch does not change any functionality.
