The branch stable/13 has been updated by markj: URL: https://cgit.FreeBSD.org/src/commit/?id=e4a51dbf5d8d75766519a8f775f30b5026227072 commit e4a51dbf5d8d75766519a8f775f30b5026227072 Author: Damien Broka <git@damien.sh> AuthorDate: 2023-09-19 16:26:06 +0000 Commit: Mark Johnston <markj@FreeBSD.org> CommitDate: 2023-10-11 13:18:25 +0000 axge: Add support for AX88179A The AX88179A has two firmware modes, one of which is backward compatible with existing AX88178A/179 driver. The active firmware mode can be controlled through a register. Update axge(4) man page to mention 179A support and ensure that, when bound to a AX88179A, the driver activates the compatible firmware mode.
