Currently for Mellanox vendor ID we don't bind vfs after moving to switchdev
because it affects VF-lAG feature, but for other features like OVS-DPDK SRIOV,
OVS-DPDK VDPA and OVS-Kernel Forwarder we have to bind them.
To support binding VFs to networking driver, there are two scenarios
that we need to address:
* Deployment case
In deployment case, we are binding vfs after moving all the
sriov_pfs to switchdev and also configuring sriov_bind service
* Reboot case
In reboot case, we start sriov_bind service which will run
after network.service sriov_config.service (The case that we are
sure that VF-LAG activation done)
