Renesas SH7757 has 2 Fast and 2 Gigabit Ether controllers, while the
'sh_eth' driver can only reset and initialize TSU of the first controller
pair. Shimoda-san tried to solve that adding the 'needs_init' member to the
'struct sh_eth_plat_data', however the platform code still never sets this
flag. I think that we can infer this information from the 'devno' variable
(set to 'platform_device::id') and reset/init the Ether controller pair
only for an even 'devno'; therefore 'sh_eth_plat_data::needs_init' can be
removed...

this is a pull request for net/master consisting of 4 patches.
The first patch is by Oliver Hartkopp, it improves the error checking
during the creation of a vxcan link. Wolfgang Grandegger's patch for the
gs_usb driver fixes the return value of the "set_bittiming" callback.
Luu An Phu provides a patch for the flexcan driver to fix the frame
length check in the flexcan_start_xmit() function. The last patch is by
Martin Lederhilger for the ems_usb driver and improves the error

* fix dynamic power save which has been broken since the driver was commited

22000 devices (previously referenced as A000) can support
short transmit queues. This means that we have less DMA
descriptors (TFD) for those shorter queues.
Previous devices must still have 256 TFDs for each queue
even if those 256 TFDs point to fewer buffers.
When I introduced support for the short queues for 22000
I broke older devices by assuming that they can also have
less TFDs in their queues. This led to several problems:
1) the payload of the commands weren't unmapped properly
which caused the SWIOTLB to complain at some point.
2) the hardware could get confused and we get hardware
crashes.

'Commit cc27b735ad3a ("PCI/portdrv: Turn off PCIe services during
shutdown")' revealed a resource leak in rtsx_pci driver during shutdown.
Issue shows up as a warning during shutdown as follows:
remove_proc_entry: removing non-empty directory 'irq/17', leaking at least
'rtsx_pci'
WARNING: CPU: 0 PID: 1578 at fs/proc/generic.c:572
remove_proc_entry+0x11d/0x130
Modules linked in <long list but none that are out-of-tree>

mp_unmap_irq
acpi_unregister_gsi_apic
acpi_pci_irq_disable
do_pci_disable_device
pci_disable_device
device_shutdown
kernel_restart
Sys_reboot
Even though rtsx_pci driver implements a shutdown callback, it is not
releasing the interrupt that it registered during probe. This is causing
the ACPI layer to complain that the shared IRQ is in use while freeing
IRQ.
This code releases the IRQ to prevent resource leak and eliminate the
warning.

When switching the driver to the managed device API, I managed to break
the case of a dual Ether devices sharing a single TSU: the 2nd Ether port
wouldn't probe. Iwamatsu-san has tried to fix this but his patch was buggy
and he then dropped the ball...
The solution is to limit calling devm_request_mem_region() to the first
of the two ports sharing the same TSU, so devm_ioremap_resource() can't
be used anymore for the TSU resource...

Note in the databook - Section 4.4 - EEE :
" The EEE feature is not supported when the MAC is configured to use the
TBI, RTBI, SMII, RMII or SGMII single PHY interface. Even if the MAC
supports multiple PHY interfaces, you should activate the EEE mode only
when the MAC is operating with GMII, MII, or RGMII interface."
Applying this restriction solves a stability issue observed on Amlogic
gxl platforms operating with RMII interface and the internal PHY.

Pull "Allwinner fixes for 4.15" from Chen-Yu Tsai:
First, one fix that adds proper regulator references for the EMAC
external PHYs on A64 boards. The EMAC bindings were developed for 4.13,
but reverted at the last minute. They were finalized and brought back
for 4.15. However in the time between, regulator support for the A64
boards was merged. When EMAC device tree changes were reintroduced,
this was not taken into account.
Second, a patch that adds OF based modalias uevent for RSB slave devices.
This has been missing since the introduction of RSB, and recently with
PMIC regulator support introduced for the A64, has been seen affecting
distributions, which have the all-important PMIC mfd drivers built as
modules, which then don't get loaded.
Other minor cleanups include final conversion of raw indices to CCU
binding macros for sun[4567]i HDMI, cleanup of dummy regulators on the
A64 SOPINE, a SD card detection polarity fix for the Orange Pi Zero
Plus2, and adding a missing compatible for the PMIC on the TBS A711
tablet.

Models such as BCM5395/97/98 and BCM53125/24/53115 and compatible require that
we turn on managed mode to actually act on Broadcom tags, otherwise they just
pass them through on ingress (host -> switch) and don't insert them in egress
(switch -> host). Turning on managed mode is simple, but requires us to
properly support ARL misses on multicast addresses which is a much more
involved set of changes not suitable for a bug fix for this release.

Display WA #1183 was recently added to workaround
"Failures when enabling DPLL0 with eDP link rate 2.16
or 4.32 GHz and CD clock frequency 308.57 or 617.14 MHz
(CDCLK_CTL CD Frequency Select 10b or 11b) used in this
enabling or in previous enabling."
This workaround was designed to minimize the impact only
to save the bad case with that link rates. But HW engineers
indicated that it should be safe to apply broadly, although
they were expecting the DPLL0 link rate to be unchanged on
runtime.
We need to cover 2 cases: when we are in fact enabling DPLL0
and when we are just changing the frequency with small
differences.
This is based on previous patch by Rodrigo Vivi with suggestions
from Ville Syrjälä.

A few spots in 3c59x missed calls to dma_mapping_error checks, casuing
WARN_ONS to trigger. Clean those up. While we're at it, refactor the
refill code a bit so that if skb allocation or dma mapping fails, we
recycle the existing buffer. This prevents holes in the rx ring, and
makes for much simpler logic
Note: This is compile only tested. Ted, if you could run this and

ENA admin command queue errors are not handled as part of ena_down().
As a result, in case of error admin queue transitions to non-running
state and aborts all subsequent commands including those coming from
ena_up(). Reset scheduled by the driver from the timer service
context would not proceed due to sharing rtnl with ena_up()/ena_down()

Under certain conditions MSI-X interrupt might arrive right after it
was unmasked in ena_up(). There is a chance it would be processed by
the driver before device ENA_FLAG_DEV_UP flag is set. In such a case
the interrupt is ignored.
ENA device operates in auto-masked mode, therefore ignoring
interrupt leaves it masked for good.
Moving unmask of interrupt to be the last step in ena_up().

commit 96ac18f14a5a ("cxgb4: Add support for new flash parts")
removed initialization of adapter->params.sf_fw_start causing issues
while flashing firmware to card. We no longer need sf_fw_start
in adapter->params as we already have macros defined for FW flash
addresses.

In some circumstances, such as with bridging, it is possible that the
stack will add a devices own MAC address to its unicast address list.
If, later, the stack deletes this address, then the i40e driver will
receive a request to remove this address.
The driver stores its current MAC address as part of the MAC/VLAN hash
array, since it is convenient and matches exactly how the hardware
expects to be told which traffic to receive.
This causes a problem, since for more devices, the MAC address is stored
separately, and requests to delete a unicast address should not have the
ability to remove the filter for the MAC address.
Fix this by forcing a check on every address sync to ensure we do not
remove the device address.
There is a very narrow possibility of a race between .set_mac and
.set_rx_mode, if we don't change netdev->dev_addr before updating our
internal MAC list in .set_mac. This might be possible if .set_rx_mode is
going to remove MAC "XYZ" from the list, at the same time as .set_mac
changes our dev_addr to MAC "XYZ", we might possibly queue a delete,
then an add in .set_mac, then queue a delete in .set_rx_mode's
dev_uc_sync and then update netdev->dev_addr. We can avoid this by
moving the copy into dev_addr prior to the changes to the MAC filter
list.
A similar race on the other side does not cause problems, as if we're
changing our MAC form A to B, and we race with .set_rx_mode, it could
queue a delete from A, we'd update our address, and allow the delete.
This seems like a race, but in reality we're about to queue a delete of
A anyways, so it would not cause any issues.
A race in the initialization code is unlikely because the netdevice has
not yet been fully initialized and the stack should not be adding or
removing addresses yet.
Note that we don't (yet) need similar code for the VF driver because it
does not make use of __dev_uc_sync and __dev_mc_sync, but instead roles
its own method for handling updates to the MAC/VLAN list, which already
has code to protect against removal of the hardware address.

linearize
The original code for __i40e_chk_linearize didn't take into account the
fact that if a fragment is 16K in size or larger it has to be split over 2
descriptors and the smaller of those 2 descriptors will be on the trailing
edge of the transmit. As a result we can get into situations where we didn't
catch requests that could result in a Tx hang.
This patch takes care of that by subtracting the length of all but the
trailing edge of the stale fragment before we test for sum. By doing this
we can guarantee that we have all cases covered, including the case of a
fragment that spans multiple descriptors. We don't need to worry about
checking the inner portions of this since 12K is the maximum aligned DMA
size and that is larger than any MSS will ever be since the MTU limit for
jumbos is something on the order of 9K.

Intel Wired LAN Driver Updates 2018-01-02
This series contains fixes for e1000 and e1000e.
Tushar Dave adds a check to the driver so that it won't attempt to disable a
device that is already disabled for e1000.
Benjamin Poirier provides a fix to e1000e, where a previous commit that
Benjamin submitted changed the meaning of the return value for
"check_for_link" for copper media and not all the instances were properly
updated. Benjamin fixes the remaining instances that needed the change.

Commit:
82c3768b8d68 ("efi/capsule-loader: Use a cached copy of the capsule header")
... refactored the capsule loading code that maps the capsule header,
to avoid having to map it several times.
However, as it turns out, the vmap() call we ended up removing did not
just map the header, but the entire capsule image, and dropping this
virtual mapping breaks capsules that are processed by the firmware
immediately (i.e., without a reboot).
Unfortunately, that change was part of a larger refactor that allowed
a quirk to be implemented for Quark, which has a non-standard memory
layout for capsules, and we have slightly painted ourselves into a
corner by allowing quirk code to mangle the capsule header and memory
layout.
So we need to fix this without breaking Quark. Fortunately, Quark does
not appear to care about the virtual mapping, and so we can simply
do a partial revert of commit:
2a457fb31df6 ("efi/capsule-loader: Use page addresses rather than struct page pointers")
... and create a vmap() mapping of the entire capsule (including header)
based on the reinstated struct page array, unless running on Quark, in
which case we pass the capsule header copy as before.

Holding locks is mandatory when calling __ib_device_get_by_index,
otherwise there are races during the list iteration with device removal.
Since the locks are static to device.c, __ib_device_get_by_index can
never be called correctly by any user out side the file.
Make the function static and provide a safe function that gets the
correct locks and returns a kref'd pointer. Fix all callers.
