Subject: [PATCH net-next] ixgbe: make macvlan on PF working when SRIOV is
enabled
When SRIOV is enabled, if we create macvlan on PF and load the VF driver in host
domain, when macvlan/PF and VF interfaces are all up, the macvlan incoming network
traffics are directed to VF interface not PF interface. This patch has fixed this
issue.
