Freescale hosts some ARMv8 based SoCs, and a generic convention
ARCH_LAYERSCAPE is used to cover such SoCs. Adding ARCH_LAYERSCAPE
to dependencies of NET_VENDOR_FREESCALE to support networking on those
SoCs.
The ARCH_LAYERSCAPE is introduced by:

The tulip driver causes annoying build-time warnings for allmodconfig
builds for all recent architectures:
dec/tulip/winbond-840.c:910:2: warning: #warning Processor architecture undefined
dec/tulip/tulip_core.c:101:2: warning: #warning Processor architecture undefined!
This is the last remaining warning for arm64, and I'd like to get rid of
it. We don't really know the cache line size, architecturally it would
be at least 16 bytes, but all implementations I found have 64 or 128
bytes. Configuring tulip for 32-byte lines as we do on ARM32 seems to
be the safe but slow default, and nobody who cares about performance these
days would use a tulip chip anyway, so we can just use that.
To save the next person the job of trying to find out what this is for
and picking a default for their architecture just to kill off the warning,
I'm now removing the preprocessor #warning and turning it into a pr_warn
or dev_warn that prints the equivalent information when the driver gets
loaded.

Commmit ac7eccd4d48fc "bnx2x: track vxlan port count" contains a bug -
Instead of achieving the required goal, vxlan configuration would not
be removed since we're decrementing the port instead of the counter.

When the R8A7795 support was added to the driver, little attention was paid
to the ravb_open() error path: free_irq() for the EMAC interrupt was called
uncoditionally, unlike request_irq(), and in a wrong order as well...
As a result, on the R-Car gen2 SoCs I started getting the following in case
of a device opening error:
WARNING: CPU: 0 PID: 1 at kernel/irq/manage.c:1448 __free_irq+0x8c/0x228()

This patch adds the PCI device ID (0xe0a1) and alx_pci_tbl entry for the
Killer E2400 Ethernet controller, modeled after the Killer E2200
controller support (0xe091) already present in the alx driver.
This patch was originally authored by Ben Pope, but it got held up by
issues in the commit message, so I'm resubmitting it on his behalf.
I've extensively used a kernel with this patch on a System76 serw9
laptop and am quite confident it works well (at least on the hardware I
have available for testing).
Note that as a favor to System76, Ubuntu has been carrying this as a
sauce patch in their 4.2 based Wily kernel, which presumably has given
it real-world testing on other E2400 equipped hardware (I don't know of
any Ubuntu kernel bugs filed about it):

new skb, we actually use it during further processing.
It's safe to ignore the new skb in the ipvlan_xmit_* functions, because
they call ipvlan_rcv_frame with local == true, so that dev_forward_skb
is called and always takes ownership of the skb.

By default the driver allowed incorrect frames to be received. What is
worse the code does not handle very short frames correctly. The FCS
length is unconditionally subtracted, and the underflow can cause
skb_put to be called with large number after implicit cast to unsigned.
And indeed, an skb_over_panic() was observed with via-velocity.
This removes the module parameter as it does not work in it's
current state, and should be implemented via NETIF_F_RXALL if needed.

Add support for IP1000A chips to dl2k driver.
IP1000A chip looks like a TC9020 with integrated PHY.
This allows IP1000A chips to work reliably because the ipg driver is
buggy - it loses packets under load and then completely stops
transmitting data.
Tested with Asus NX1101 v2.0 at 10, 100 and 1000Mbps:
vendor=0x13f0 device=0x1023 (rev 0x41)
subsystem vendor=0x1043 device=0x8180
MAC address registers access needed to be changed from 8-bit to 16-bit
because 8-bit does not work on IP1000A. 8-bit access is not even
allowed in the TC9020 datasheet (although it worked). 16-bit access
works on both.
Tested that it does not break D-Link DGE-550T (DL-2000 chip, probably
a rebranded TC9020):

Commit 05cc5a39ddb7 "bnx2x: add vlan filtering offload" introduced
a regression in regard for vlans for 57710, 57711 adapters -
Loading 8021q module on a machine with such an adapter would cause
a null pointer dereference, as the driver mistakenly publishes it
has capabilities for vlan CTAG filtering.

Remove rsstable array and its initialization from be_set_rss_hash_opts().
The array became unused after "e255787 be2net: Support for configurable
RSS hash key". The initial RSS table is now filled and stored for later
usage during Rx queue creation.

When RX/TX interrupt for Network Control queue and Best Effort queue
is issued at the same time, the interrupt mask of Network Control
queue will be reset when the mask of Best Effort queue is set.
This patch fixes this problem.

On certain hardware after software reboot the chip may get stuck and fail
to reinitialize during reset. This can be fixed by ensuring that PHY is
reset too.
Old PHY resetting method required operational MDIO interface, therefore
the chip should have been already set up. In order to be able to function
during probe, it is changed to use PMT_CTRL register.
The problem could be observed on SMDK5410 board.

commit a70587b3389a ("ath10k: configure copy engine 5 for HTT messages")
moved send completion polling under HTT Rx (CE 5) service routine. For
QCA6174 based devices copy engine 1 (CE 1) is used for HTT Rx instead
of CE 5. So send completion never be called. This is causing "failed to
transmit packet, dropping: -105" errors. Fix this by processing send
completion from CE 1 service routine instead of CE 5.

Commit 77a993942 "phy/at8031: enable at8031 to work on interrupt mode"
added interrupt support for the 8031 PHY but left out the other two
chips supported by this driver.
This patch sets the .ack_interrupt and .config_intr functions for the
8030 and 8035 drivers as well.

Currently it's assumed that firmware exports only the class of sensors
supported by the driver. However with newer firmware or SCPI protocol
revision, support for newer classes of sensors can be present.
The driver fails to probe with the following warning if an unsupported
class of sensor is encountered in the firmware.
sysfs: cannot create duplicate filename
'/devices/platform/scpi/scpi:sensors/hwmon/hwmon0/'
------------[ cut here ]------------
WARNING: at fs/sysfs/dir.c:31

PC is at sysfs_warn_dup+0x54/0x78
LR is at sysfs_warn_dup+0x54/0x78
This patch fixes the above issue by skipping through the unsupported
class of SCPI sensors.

The newly added scpi thermal support is broken when the scpi driver
is built-in but the thermal driver is a loadable module:
drivers/built-in.o: In function `scpi_hwmon_probe':
(.text+0x444d70): undefined reference to `thermal_zone_of_sensor_unregister'
(.text+0x444d94): undefined reference to `thermal_zone_of_sensor_register'
drivers/built-in.o: In function `scpi_hwmon_remove':
(text+0x444e6c): undefined reference to `thermal_zone_of_sensor_unregister'
This uses the same Kconfig trick that we have in a couple of other
drivers already to ensure we can only select the driver in valid
configurations when either THERMAL_OF is disabled, or when with a
dependency on CONFIG_THERMAL that can force SCPI to be a loadable
module in the case I was hitting.
