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.

v2:
 - 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.
