From 9410733c44d768b085af3877ccf63efa298168e9 Mon Sep 17 00:00:00 2001 From: Ilan Tayari Date: Wed, 14 Jun 2017 10:19:54 +0300 Subject: [PATCH] net/mlx5: FPGA, Move FPGA init/cleanup to init_once The FPGA init and cleanup routines should be called just once per device. Move them to the init_once and cleanup_once routines.
