The branch stable/13 has been updated by bz: URL: https://cgit.FreeBSD.org/src/commit/?id=57d5000e593b73c335aed7dc0db96596a68aa3a2 commit 57d5000e593b73c335aed7dc0db96596a68aa3a2 Author: Bjoern A. Zeeb <bz@FreeBSD.org> AuthorDate: 2021-03-30 15:58:55 +0000 Commit: Bjoern A. Zeeb <bz@FreeBSD.org> CommitDate: 2021-07-18 00:34:59 +0000 mlx5: remove dependency on ifnet specifics of linux/netdevice.h Rename the last remaining bits depending on ifnet from linux/netdevice.h instead of using the compat macros. This helps clearing up struct netdevice being struct ifnet from linux/netdevice.h.
