The branch main has been updated by imp: URL: https://cgit.FreeBSD.org/src/commit/?id=55747938b5c4c913f742fd03189f0c660ced7bef commit 55747938b5c4c913f742fd03189f0c660ced7bef Author: Evgeni Golov <evgeni@debian.org> AuthorDate: 2023-02-27 22:50:56 +0000 Commit: Warner Losh <imp@FreeBSD.org> CommitDate: 2023-02-27 22:51:27 +0000 if_re: Generate an address if there is none in the EEPROM There exists hardware that has no ethernet address burned into the EEPROM. Loading if_re on such a HW brings the device up with '00:00:00:00:00:00' as the address, and that doesn't get you too far in a real network.
