From ded6e16b37e4c8c86cda98604ecd78818d6ca36a Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Mon, 4 Oct 2021 12:14:43 -0700 Subject: mlx4: replace mlx4_mac_to_u64() with ether_addr_to_u64() mlx4_mac_to_u64() predates and opencodes ether_addr_to_u64(). It doesn't make the argument constant so it'll be problematic when dev->dev_addr becomes a const. Convert to the generic helper.
