Hi grive:

I’m using the bond4 mode of the mlx5 NIC, I have two ports.

Now I want to implement the hotplug function based on the failsafe module.

I've verified that the sub-device is two ports and it works well:

--vdev, ‘net_failsafe0,mac=04:e8:92:7d:dd:e5,dev(08:00.0),dev(08:00.1)’, -b, ‘08:00.0’, -b,’ 08:00.1’

I wonder if subdevieces can be a bonding, and if so, how should I configure it?

So far, I’ve verified that the following configuration does not work:

"--vdev", "net_bonding0,mac=04:e8:92:7d:dd:e4,mode=4,slave=0000:08:00.0,slave=0000:08:00.1,xmit_policy=l34","--vdev", "net_failsafe0,mac=04:e8:92:7d:dd:e5,dev(08:00.0),dev(08:00.1)",  "-b", "08:00.0", "-b", "08:00.1"

"--vdev", "net_bonding0,mac=04:e8:92:7d:dd:e4,mode=4,slave=0000:08:00.0,slave=0000:08:00.1,xmit_policy=l34","--vdev", "net_failsafe0,mac=04:e8:92:7d:dd:e5,dev(net_bonding0)"

"--vdev", "net_bonding0,mac=04:e8:92:7d:dd:e4,mode=4,slave=0000:08:00.0,slave=0000:08:00.1,xmit_policy=l34","--vdev", "net_failsafe0,mac=04:e8:92:7d:dd:e5,dev(08:00.0),dev(08:00.1)"

Thanks!
