From ea99d227f95f6849d5523e8d327b1805bb828254 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Wed, 26 Apr 2023 13:04:58 -0300 Subject: [PATCH] smegw01: Read the second MAC address Currently, only the first MAC address is read from the fuses. The second MAC address is not read and Linux assigns a random one. To prevent this behavior, read the second MAC address from the fuses and store it into the eth1addr environment variable so that it can be passed to Linux.
