The presence of an allocated RIF in mlxsw_sp->router->rifs[rif_index] marks
that rif_index as taken.
Set the marking of a taken RIF to happen before calling ops->create in
order to allow creation of a GRE underlay RIF, which may be allocated and
created as part of an overlay RIF creation.

In Spectrum-2, the underlay routing table is pointed by an underlay router
interface in contrary to Spectrum where only an underlay virtual router
should be set. That makes the underlay virtual router field in RITR
reserved for Spectrum-2.

Change loopback RIF creation function to support the new underlay RIF
field, however leave this field reserved for Spectrum-1 updates.

Accessing the phy_device indirectly via the netdevice causes few issues:
- Accessing the phy_device when it's not attached may cause a NPE.
- If we have to access the phy_device when it's not attached we have
  to use mdiobus_get_phy() to get a reference to the phy_device.

Therefore store a phy_device reference in struct rtl8169_private directly.

Triggering an asynchronous reset is problematic for the following
reasons, therefore reset the chip synchronously.

- The reset routine resets registers and parameters behind our back
  what may collide with code executed after triggering the reset.

- __rtl8169_resume() is called as part of pm_runtime_get_sync() and
  callers expect that the chip is fully resumed afterwards.

In context of this driver triggering an asynchonous reset should be
considered an emergency procedure.

net: use strict checks in doit handlers

This series extends strict argument checking to doit handlers
of the GET* nature.  This is a bit tricky since strict checking
flag has already been released..

iproute2 did not have a release with strick checks enabled,
and it will only need a minor one-liner to pass strick checks
after all the work that DaveA has already done.

Big thanks to Dave Ahern for help and guidence.

 - remove unnecessary check in patch 5 (Nicolas);
 - add path 7 (DaveA);

On multiqueue network devices, RPS maps are configured independently
for each receive queue through /sys/class/net/$DEV/queues/rx-*.

On virtio-net currently all packets use the map from rx-0, because the
real rx queue is not known at time of map lookup by get_rps_cpu.

Call skb_record_rx_queue in the driver rx path to make lookup work.

Recording the receive queue has ramifications beyond RPS, such as in
sticky load balancing decisions for sockets (skb_tx_hash) and XPS.
