====================
liquidio: switchdev support for LiquidIO NIC

patch1 of this patch set adds switchdev support for SRIOV capable
LiquidIO NIC, so that for every SRIOV VF on LiquidIO, a representor
netdev is created on hypervisor. It also has changes to send representor
interface configurations like admin state and MTU to LiquidIO firmware and
to retrieve HW counted VF stats for VF representor.

patch2 adds support for switchdev enable/disable from devlink

Patchset Change Log:
  V2 -> V3:
    * Use mac address as the physical switchID.
    * Check for eswitch_mode before returning switchID

  V1 -> V2:
    * Name the representors "pfXvfY".
    * Drop patch3 (ethtool support for switchdev ports) that was in V1
      because it's not necessary.
