I tested following scenario on 0.107.1-3ubuntu0.22.04.3:
ubuntu@romano:~$ cat /etc/netplan/99-bond.yaml
network:
version: 2
ethernets:
ens7f0:
virtual-function-count: 16
embedded-switch-mode: switchdev
delay-virtual-functions-rebind: true
ens7f1:
virtual-function-count: 16
embedded-switch-mode: switchdev
delay-virtual-functions-rebind: true
bonds:
bond0:
interfaces:
- ens7f0
- ens7f1
parameters:
mode: active-backup
bond created as expected:
ubuntu@romano:~$ cat /proc/net/bonding/bond0
Ethernet Channel Bonding Driver: v5.15.0-174-generic
Bonding Mode: fault-tolerance (active-backup)
Primary Slave: None
Currently Active Slave: ens7f1
MII Status: up
MII Polling Interval (ms): 0
Up Delay (ms): 0
Down Delay (ms): 0
Peer Notification Delay (ms): 0
Slave Interface: ens7f1
MII Status: up
Speed: 100000 Mbps
Duplex: full
Link Failure Count: 0
Permanent HW addr: b8:3f:d2:2d:68:7f
Slave queue ID: 0
Slave Interface: ens7f0
MII Status: up
Speed: Unknown
Duplex: Unknown
Link Failure Count: 0
Permanent HW addr: b8:3f:d2:2d:68:7e
Slave queue ID: 0
Both interfaces switch to eswitch mode:
ubuntu@romano:~$ sudo devlink dev eswitch show pci/0000:61:00.0
pci/0000:61:00.0: mode switchdev inline-mode none encap-mode basic
ubuntu@romano:~$ sudo devlink dev eswitch show pci/0000:61:00.1
pci/0000:61:00.1: mode switchdev inline-mode none encap-mode basic
Both PFs created 16 VFs:
