Bonding in active-backup mode with VF

Hi all,

Can someone confirm that if one wants to configure active-backup bonding with 2 VFs, the fail_over_mac option should be set to 1?

According to my experiments and web searches, it looks like this is the only supported option but the "Configuring QoS Features with Intel Flexible Port Partitioning" document [1] doesn't give much details about it.

Thanks in advance for your inputs,

Simon
