[next-queue v6 PATCH 0/7] i40e: Add port representor and initial switchdev support

[Sridhar Samudrala <sridhar.samudrala@intel.com>]

- Patch 1 introduces devlink interface to get/set the mode of switch.
- Patch 2 adds support to create control plane port representor netdevs
  associated with dataplane PF and VFs that can be used to control/configure
  PF/VFs even when they are in a different namespace.
- Patch 3 enables syncing link state between PF/VFs and associated Port
  representors.
- Patch 4 adds a new type to metadata_dst to allow passing port id to lower
  device.
- Patch 5 adds TX and RX support to port netdevs.
- Patch 6 enables HW and SW Port statistics to be exposed via netlink on
  Port netdevs.
- Patch 7 adds support to get switch id and port number for Port netdevs.

v6:
- Port representor netdevs are created and supported for PFs too.
- Broadcast filters are not disabled by default on VFs in switchdev mode.
  Instead, offload_fwd_mark is set on skb's that are forwarded to Port
  netdevs to indicate that the HW has done the forwarding.
- Random mac addresses are assigned to Port netdevs.
v5:
- Fix an issue with the link state sync patch.
v4:
- Make VFPR ndo_get_stats64 a void function to match with recent upstream
  change.
v3:
- misc. error handling fixes suggested by Scott Peterson
- introduce switchdev_ops and add support to get switch id and port no.
  for VFPR netdevs. Suggested by Or Gerlitz
v2:
- handle i40e_alloc_vfpr_netdev() failures.
- minor comment/commit msg updates.
