I have been using a Beaglebone Black for a project for years. I recently upgraded from Dunfell to Gatesgarth and again began experiencing a problem with the ethernet interface failing to come online 10% of the time, a problem which can only be fixed by a power cycle (not a reboot). This is a well known problem documented by this thread ( https://groups.google.com/g/beagleboard/c/9mctrG26Mc8 ) going back over 7 years. It's a hardware problem, but it does have a software fix. But that fix must have been left out of recent meta-bbb builds. I believe previous fixes have been something like this patch ( https://github.com/RobertCNelson/bb-kernel/blob/607ae2e36477357a4bb222f285fd7460d5230ab9/patches/net/0009-cpsw-search-for-phy.patch ). That old patch targets the 3.15 kernel and I believe Gatesgarth is using 5.10. Should I expect that patch to work unmodified on 5.10? I don't know low level kernel mechanics well enough to understand what it's really doing. If that patch won't work, does anyone know how I could proceed to get ethernet working on the Beaglebone Black with current versions of Yocto?
