a check that triggers a warning in r8169, see [0].

Add rtl_disable_exit_l1() for ensuring that the chip doesn't
inadvertently exit ASPM L1 when being in a low-power mode.
The new function is called from rtl_prepare_power_down() which
has to be moved in the code to avoid a forward declaration.
According to Realtek OCP register 0xc0ac shadows ERI register 0xd4
on RTL8168 versions from RTL8168g. This allows to simplify the

Pull power management updates from Rafael Wysocki:
"The most signigicant change here is the addition of a new cpufreq
'P-state' driver for AMD processors as a better replacement for the
venerable acpi-cpufreq driver.
There are also other cpufreq updates (in the core, intel_pstate, ARM
drivers), PM core updates (mostly related to adding new macros for
declaring PM operations which should make the lives of driver
developers somewhat easier), and a bunch of assorted fixes and
cleanups.

With newer chip versions ASPM-related issues seem to occur only if
L1.2 is enabled. I have a test system with RTL8168h that gives a
number of rx_missed errors when running iperf and L1.2 is enabled.
With L1.2 disabled (and L1 + L1.1 active) everything is fine.
See also [0]. Can't test this, but L1 + L1.1 being active should be
sufficient to reach higher package power saving states.

ASPM is disabled completely because we've seen different types of
problems in the past. However it seems these problems occurred with
L1 or L1 sub-states only. On all the chip versions I've seen the
acceptable L0s exit latency is 512ns. This should be short enough not
to cause problems. If the actual L0s exit latency of the PCIe link
is bigger than 512ns then the PCI core will disable L0s anyway.
So let's give it a try and disable L1 and L1 sub-states only.

Add the segment number to the device name to make it more unique.
This fixes operation on ARM N1SDP boards, with two boards connected
together to form an SMP system, and all on-board devices showing up
twice, just on different PCI segments. A similar issue would occur on
large systems with many PCI slots and multiple RTL8169 NICs.
Fixes: f1e911d5d0dfd ("r8169: add basic phylib support")

Trivial conflicts in net/can/isotp.c and
tools/testing/selftests/net/mptcp/mptcp_connect.sh
scaled_ppm_to_ppb() was moved from drivers/ptp/ptp_clock.c
to include/linux/ptp_clock_kernel.h in -next so re-apply
the fix there.

In preparation for FORTIFY_SOURCE performing compile-time and run-time
field bounds checking for memcpy(), memmove(), and memset(), avoid
intentionally reading across neighboring array fields.
The memcpy() is copying the entire structure, not just the first array.
Adjust the source argument so the compiler can do appropriate bounds
checking.

It has been reported that on RTL8106e the link-up interrupt may be
significantly delayed if the user enables ASPM L1. Per default ASPM
is disabled. The change leaves L1 enabled on the PCIe link (thus still
allowing to reach higher package power saving states), but the
NIC won't actively trigger it.

In preparation to enable -Wimplicit-fallthrough for Clang, fix a warning
by explicitly adding a break statement instead of letting the code fall
through to the next case.
