[systemd-devel] [PATCH] restore support for enslaving to bonding interface

[Mark Oteiza]

networkd: Restore logic for enslaving to a master bonding interface.
---

Bonding support seems to have been removed right after being added,
between 52433f6 (22 Jan) and 54abf46 (25 Jan).

http://cgit.freedesktop.org/systemd/systemd/log/src/network/networkd-link.c

With this patch, networkd successfully configures the links.

Currently, networkd will not dhcp on the bonding interface.  Here is my
configuration:

# /etc/systemd/network/dhcp.network
[Match]
Name=bond0

[Network]
DHCP=true

# /etc/systemd/network/ethernet.network
[Match]
Name=enp5s0

[Network]
Bond=bond0

# /etc/systemd/network/virtual.netdev
[NetDev]
Name=bond0
Kind=bond

# /etc/systemd/network/wireless.network
[Match]
Name=wlp2s0

[Network]
Bond=bond0

… and the network after manually adding address/route to bond0:
$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo

$ ip r
