Some of the error messages that are printed by the interrupt handlers
are poorly written. For example, many don't include a device prefix,
so there's no indication that they are EMAC errors.
Also use rate limiting for all messages that could be printed from
interrupt context.

The EMAC has a restriction that the upper 32 bits of the base addresses
for the RFD and RRD rings must be the same. The ensure that restriction,
we allocate twice the space for the RRD and locate it at an appropriate
address.
We also re-arrange the allocations so that invalid addresses are even
less likely.

The EMAC is capable of multiple TX and RX rings, but the driver only
supports one ring for each. One function had some left-over unused
code that supports multiple rings, but all it did was make the code
harder to read.

The 64/32-bit DMA mask hackery in the EMAC driver is not actually necessary,
and is technically not accurate. The EMAC hardware is limted to a 45-bit
DMA address. Although no EMAC-enabled system can have that much DDR,
an IOMMU could possible provide a larger address. Rather than play games
with the DMA mappings, the driver should provide a correct value and
trust the DMA/IOMMU layers to do the right thing.

rtl_init_one() currently enables PCI wakeups if the ethernet device
is found to be WOL-capable. There is no need to do this when
rtl8169_set_wol() will correctly enable or disable the same wakeup flag
when WOL is activated/deactivated.
This works around an ACPI DSDT bug which prevents the Acer laptop models
Aspire ES1-533, Aspire ES1-732, PackardBell ENTE69AP and Gateway NE533
from entering S3 suspend - even when no ethernet cable is connected.
On these platforms, the DSDT says that GPE08 is a wakeup source for
ethernet, but this GPE fires as soon as the system goes into suspend,
waking the system up immediately. Having the wakeup normally disabled
avoids this issue in the default case.
With this change, WOL will continue to be unusable on these platforms
(it will instantly wake up if WOL is later enabled by the user) but we
do not expect this to be a commonly used feature on these consumer
laptops. We have separately determined that WOL works fine without any
ACPI GPEs enabled during sleep, so a DSDT fix or override would be
possible to make WOL work.

Add support for the TI DP83822 10/100Mbit ethernet phy.
The DP83822 provides flexibility to connect to a MAC through a
standard MII, RMII or RGMII interface.
In addition the DP83822 needs to be removed from the DP83848 driver
as the WoL support is added here for this device.

When both user ports are joined to the same bridge, the normal
HW MAC learning is enabled. This means that unicast traffic is forwarded
in HW.
If one of the user ports leave the bridge,
the ports goes back to the initial separated operation.
Port separation relies on disabled HW MAC learning. Hence the condition
that both ports must join same bridge.
Add brigde methods port_bridge_join, port_bridge_leave and
port_stp_state_set.

1GbE Intel Wired LAN Driver Updates 2017-10-10
This series contains updates to e1000e and igb.
Benjamin Poirier provides several fixes for e1000e, starting with a
correction to the return status which was always returning success even
if it was not successful. Fixed code comments to reflect the actual
code behavior. Fixed the conditional test for the correct return
value. Fixed a potential race condition reported by Lennart Sorensen,
where the single flag get_link_status is used to signal two different
states.
Sasha fixes a buffer overrun for i219 devices, where the chipset had
reduced the round-trip latency for the LAN controller DMA accesses
which in some high performance cases caused a buffer overrun while
processing the DMA transactions.
Willem de Bruijn changes the default behavior of e1000e to use the
burst mode settings by default unless the user specifies the
receive interrupt delay (RxIntDelay).
Florian Fainelli updates the driver to differentiate between when
e1000e_put_txbuf() is called from normal reclamation or when a
DMA mapping failure to make the driver more "drop monitor friendly".
Christophe JAILLET fixes a potential NULL pointer dereference by
properly returning -ENOMEM on memory allocation failures.

Devices that support FLAG2_DMA_BURST have different default values
for RDTR and RADV. Apply burst mode default settings only when no
explicit value was passed at module load.
The RDTR default is zero. If the module is loaded for low latency
operation with RxIntDelay=0, do not override this value with a burst
default of 32.
Move the decision to apply burst values earlier, where explicitly
initialized module variables can be distinguished from defaults.

Intel® 100/200 Series Chipset platforms reduced the round-trip
latency for the LAN Controller DMA accesses, causing in some high
performance cases a buffer overrun while the I219 LAN Connected
Device is processing the DMA transactions. I219LM and I219V devices
can fall into unrecovered Tx hang under very stressfully UDP traffic
and multiple reconnection of Ethernet cable. This Tx hang of the LAN
Controller is only recovered if the system is rebooted. Slightly slow
down DMA access by reducing the number of outstanding requests.
This workaround could have an impact on TCP traffic performance
on the platform. Disabling TSO eliminates performance loss for TCP
traffic without a noticeable impact on CPU performance.

When e1000e_poll() is not fast enough to keep up with incoming traffic, the
adapter (when operating in msix mode) raises the Other interrupt to signal
Receiver Overrun.
This is a double problem because 1) at the moment e1000_msix_other()
assumes that it is only called in case of Link Status Change and 2) if the
condition persists, the interrupt is repeatedly raised again in quick
succession.
Ideally we would configure the Other interrupt to not be raised in case of
receiver overrun but this doesn't seem possible on this adapter. Instead,
we handle the first part of the problem by reverting to the practice of
reading ICR in the other interrupt handler, like before commit 16ecba59bc33
("e1000e: Do not read ICR in Other interrupt"). Thanks to commit
0a8047ac68e5 ("e1000e: Fix msi-x interrupt automask") which cleared IAME
from CTRL_EXT, reading ICR doesn't interfere with RxQ0, TxQ0 interrupts
anymore. We handle the second part of the problem by not re-enabling the
Other interrupt right away when there is overrun. Instead, we wait until
traffic subsides, napi polling mode is exited and interrupts are
re-enabled.

Lennart reported the following race condition:
\ e1000_watchdog_task
\ e1000e_has_link
\ hw->mac.ops.check_for_link() === e1000e_check_for_copper_link
/* link is up */
mac->get_link_status = false;
/* interrupt */
\ e1000_msix_other
hw->mac.get_link_status = true;
link_active = !hw->mac.get_link_status
/* link_active is false, wrongly */
This problem arises because the single flag get_link_status is used to
signal two different states: link status needs checking and link status is
down.
Avoid the problem by using the return value of .check_for_link to signal
the link status to e1000e_has_link().

It looks like we weren't correctly placing the pages from buffers that had
been used to return a filter programming status back on the ring. As a
result they were being overwritten and tracking of the pages was lost.
This change works to correct that by incorporating part of
i40e_put_rx_buffer into the programming status handler code. As a result we
should now be correctly placing the pages for those buffers on the
re-allocation list instead of letting them stay in place.

40GbE Intel Wired LAN Driver Updates 2017-10-09
This series contains updates to i40e and i40evf only.
Jake fixes missed flag conversion from u64 to u32. Fixes a deafult ITR
value issue where the driver defaults to an ITR value of half the
expected value (in terms of minimum microseconds between interrupts). So
fix this by changing the default values to be calculated using the
ITR_REG_TO_USEC() macro which indicates that we are converting from the
register units into microseconds. Updates the drivers to bump the tail in
increments of 8 and double the number of descriptors we will bundle into
one tail bump when receiving. With the recent kernel support for
enabling XPS and QoS at the same time, we no longer need to worry about
the number of traffic classes when enabling XPS.
Lihong converts the use of hash_for_each() to hash_for_each_safe() to
safely remove a hash entry. Adds a check for the return value for
find_first_bit() in the case that it returns the size passed to search.
Alan fixes a bug in which filters are erroneously removed if they are
removed and then added again. So make sure that when adding a filter, if
we find it already existed in our list, make sure it is not marked to be
removed.
Jayaprakash adds the retrying of PHY reads when the I2C is busy for a
maximum period of 500ms.
Rami fixes code comment typo.

Bhumika Goyal fixes a couple of instances which were overlooked when we
made ixgbe_mac_operations constant.
Shannon Nelson fixes an issue to restore normal operations after the
last MACVLAN offload is removed, otherwise we get stuck in a single queue
operations.
The infamous Jesper Dangaard Brouer adds a counter which counts the
number of times the recycle fails and the real page allocator is invoked.
Alex updates the adaptive ITR algorithm to better support the needs of the
network. This attempt to make it so that our ITR algorithm will try to
prevent either starving a socket buffer for memory in the case of
transmit, or overrunning an receive socket buffer on receive. We should
function better with new features like XDP which can handle small packets
at high rates without needing to lock us into NAPI polling mode.

The u-blox TOBY-L2 is a LTE Cat 4 module with HSPA+ and 2G fallback.
This module allows switching to different USB profiles with the
'AT+UUSBCONF' command, and provides a ECM network interface when the
'AT+UUSBCONF=2' profile is selected.
The u-blox SARA-U2 is a HSPA module with 2G fallback. The default USB
configuration includes a ECM network interface.
Both these modules are controlled via AT commands through one of the
TTYs exposed. Connecting these modules may be done just by activating
the desired PDP context with 'AT+CGACT=1,<cid>' and then running DHCP
on the ECM interface.

This patch fixes a typo in i40e_vsi_alloc_arrays() documentation.
The first parameter name should be "vsi" instead of "type".

The computed result of I40E_MAX_VSI_QP * I40E_VIRTCHNL_SUPPORTED_QTYPES
is used more than three times in function i40e_config_irq_link_list.
Simply declare a local variable to store it to improve readability.
