Add the commands to set and show the mode of SRIOV E-Switch, two modes
are supported:
* legacy: operating in the "old" L2 based mode (DMAC --> VF vport)
* switchdev: the E-Switch is referred to as whitebox switch configured
using standard tools such as tc, bridge, openvswitch etc. To allow
working with the tools, for each VF, a VF representor netdevice is
created by the E-Switch manager vendor device driver instance (e.g PF).
