From 92040c6daaa46027c2d11aab0a5366ab667c5358 Mon Sep 17 00:00:00 2001 From: Arthur Kiyanovski Date: Wed, 26 Feb 2020 12:03:35 +0200 Subject: [PATCH] net: ena: fix broken interface between ENA driver and FW In this commit we revert the part of commit 1a63443afd70 ("net/amazon: Ensure that driver version is aligned to the linux kernel"), which breaks the interface between the ENA driver and FW. We also replace the use of DRIVER_VERSION with DRIVER_GENERATION when we bring back the deleted constants that are used in interface with ENA device FW. This commit does not change the driver version reported to the user via ethtool, which remains the kernel version.
