As reported in [0] at least one RTL8168dp version has problems
establishing a link. This chip version has an integrated RTL8211b PHY,
however the chip seems to report a wrong PHY ID, resulting in a wrong
PHY driver (for Generic Realtek PHY) being loaded.
Work around this issue by adding a hook to r8168dp_2_mdio_read()
for returning the correct PHY ID.

Since it became possible for the DSA core to use a CPU port different
than 8, our bcm_sf2_imp_setup() function was broken because it assumes
that registers are applicable to port 8. In particular, the port's MAC
is going to stay disabled, so make sure we clear the RX_DIS and TX_DIS
bits if we are not configured for port 8.

Historically linux tried to stick to RFC 791, 1122, 2003
for IPv4 ID field generation.
RFC 6864 made clear that no matter how hard we try,
we can not ensure unicity of IP ID within maximum
lifetime for all datagrams with a given source
address/destination address/protocol tuple.
Linux uses a per socket inet generator (inet_id), initialized
at connection startup with a XOR of 'jiffies' and other
fields that appear clear on the wire.
Thiemo Nagel pointed that this strategy is a privacy
concern as this provides 16 bits of entropy to fingerprint
devices.
Let's switch to a random starting point, this is just as
good as far as RFC 6864 is concerned and does not leak
anything critical.

The limitation was mixed matchers in which the outer header IP version

During connection tracking offloads with high number of connections,
(40K connections per second), flow table group lock contention is
observed.
To improve the performance by reducing lock contention, lockless
FTE read lookup is performed as described below.
Each flow table entry is refcounted.
Flow table entry is removed when refcount drops to zero.
rhash table allows rcu protected lookup.
Each hash table entry insertion and removal is write lock protected.
Hence, it is possible to perform lockless lookup in rhash table using
following scheme.
(a) Guard FTE entry lookup per group using rcu read lock.
(b) Before freeing the FTE entry, wait for all readers to finish
accessing the FTE.
Below example of one reader and write in parallel racing, shows
protection in effect with rcu lock.

Intel Wired LAN Driver Updates 2019-11-01
This series contains updates to e1000, igb, igc, ixgbe, i40e and driver
documentation.
Lyude Paul fixes an issue where a fatal read error occurs when the
device is unplugged from the machine. So change the read error into a
warn while the device is still present.
Manfred Rudigier found that the i350 device was not apart of the "Media
Auto Sense" feature, yet the device supports it. So add the missing
i350 device to the check and fix an issue where the media auto sense
would flip/flop when no cable was connected to the port causing spurious
kernel log messages.
I fixed an issue where the fix to resolve receive buffer starvation was
applied in more than one place in the driver, one being the incorrect
location in the i40e driver.
Wenwen Wang fixes a potential memory leak in e1000 where allocated
memory is not properly cleaned up in one of the error paths.
Jonathan Neuschäfer cleans up the driver documentation to be consistent
and remove the footnote reference, since the footnote no longer exists in
the documentation.
Igor Pylypiv cleans up a duplicate clearing of a bit, no need to clear
it twice.

At least on the i350 there is an annoying behavior that is maybe also
present on 82580 devices, but was probably not noticed yet as MAS is not
widely used.
If no cable is connected on both fiber/copper ports the media auto sense
code will constantly swap between them as part of the watchdog task and
produce many unnecessary kernel log messages.
The swap code responsible for this behavior (switching to fiber) should
not be executed if the current media type is copper and there is no signal
detected on the fiber port. In this case we can safely wait until the
AUTOSENSE_EN bit is cleared.

some places).
Otherwise it's all fairly run of the mill fixes, i915, panfrost,
etnaviv, v3d and radeon, along with a core scheduler fix.
Summary:
amdgpu:
- clang alignment fixes
- Updated golden settings
- navi: gpuvm, sdma and display fixes
- Freesync fix
- Gamma fix for DCN
- DP dongle detection fix
- vega10: Fix for undervolting
radeon:
- reenable kexec fix for ppc
scheduler:
- set an error if hw job failed
i915:
- fix PCH reference clock for HSW/BDW
- TGL display PLL doc fix
panfrost:
- warning fix
- runtime pm fix
- bad pointer dereference fix
v3d:
- memleak fix
etnaviv:
- memory corruption fix
- deadlock fix
- reintroduce lost debug message"

Fix a recently introduced (mostly theoretical) issue that the requests
to confine the maximum CPU frequency coming from the platform firmware
may not be taken into account if multiple CPUs are covered by one
cpufreq policy on a system with ACPI.

A copule of regression fixes and a fix for mutex deadlock at
hog-unplug, as well as other device-specific fixes:
- A commit for avoiding the spurious unsolicited interrupt on HD-
audio bus caused a stall at shutdown, so it's reverted now.
- The recent support of AMD/Nvidia audio component binding caused
a mutex deadlock; fixed by splitting to another mutex
- The device hot-unplug and the ALSA timer close combo may lead to
another mutex deadlock; fixed by moving put_device() calls
- Usual device-specific small quirks for HD- and USB-audio drivers
- An old error check fix in FireWire driver

A typo in nfs4_refresh_delegation_stateid() means we're leaking an
RCU lock, and always returning a value of 'false'. As the function
description states, we were always supposed to return 'true' if a
matching delegation was found.

This reverts commit 5bc60de50d ("selftests: bpf: Don't try to read
files without read permission").
Quoted commit does not work at all, and was never tested.
Script requires root permissions (and tests for them)
and os.access() will always return true for root.
The correct fix is needed in the bpf tree, so let's just
revert and save ourselves the merge conflict.

The Broadcom Brahma-B53 core is susceptible to the issue described by
ARM64_ERRATUM_843419 so this commit enables the workaround to be applied
when executing on that core.
Since there are now multiple entries to match, we must convert the
existing ARM64_ERRATUM_843419 into an erratum list and use
cpucap_multi_entry_cap_matches to match our entries.
