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).

OK I can't come up with a better name and Jiri/Or convinced me this
should work ok so this works for me.

cool.

One question though going forward. We have devices with multiple
"switches" in them how does this work in a devlink environment? Do
we need some way to enumerate the switches and identify them. In
which case this attribute would be a global setting.

Devices which expose single PCI function for managing multiple switches?

AFAIK the driver for this HW is not upstream yet, there's no real
legacy around them. Since we agree the new mode is the way to go,
global setting should be fine here, I think.
