The mlx4 driver reacts on netdev events generated by bonding when slave state changes happen by programming a HW V2P (Virt-to-Phys) port table. Bonding was extended to expose these state changes through netdev events. When an mlx4 interface such as the mlx4 IB/RoCE driver is subject to this policy, QPs are created over virtual ports which are mapped to one of the two physical ports. When a failure happens, the re-programming of the V2P table allows traffic to keep flowing. The mlx4 Ethernet driver interfaces are not subject to this policy and act as usual. A 2nd use-case for this model would be to add HA and Link Aggregation support to single ported mlx4 Ethernet VFs. In this case, the PF Ethernet intrfaces are bonded, all the VFs see single port devices (which is supported already today), and VF QPs are subject to V2P. Moni and Or.
