r8153 on Dell TB15/16 dock corrupts rx packets.
This change is suggested by Realtek. They guess that the XHCI controller
doesn't have enough buffer, and their guesswork is correct, once the RX
aggregation gets disabled, the issue is gone.
ASMedia is currently working on a real sulotion for this issue.
Dell and ODM confirm the bcdDevice and iSerialNumber is unique for TB16.
Note that TB15 has different bcdDevice and iSerialNumber, which are not
unique values. If you still have TB15, please contact Dell to replace it
with TB16.

tfile->tun could be detached before we close the tun fd,
via tun_detach_all(), so it should not be used to check for
tfile->tx_array.
As Jason suggested, we probably have to clean it up
unconditionally both in __tun_deatch() and tun_detach_all(),
but this requires to check if it is initialized or not.
Currently skb_array_cleanup() doesn't have such a check,
so I check it in the caller and introduce a helper function,
it is a bit ugly but we can always improve it in net-next.

Due to architecture limitations, the IBM VNIC client driver is unable
to perform MAC address changes unless the device has "logged in" to
its backing device. Currently, pending MAC changes are handled before
login, resulting in an error and failure to change the MAC address.
Moving that chunk to the end of the ibmvnic_login function, when we are
sure that it was successful, fixes that.
The MAC address can be changed when the device is up or down, so
only check if the device is in a "PROBED" state before setting the
MAC address.

ppp_dev_uninit(), which is the .ndo_uninit() handler of PPP devices,
needs to lock pn->all_ppp_mutex. Therefore we mustn't call
register_netdevice() with pn->all_ppp_mutex already locked, or we'd
deadlock in case register_netdevice() fails and calls .ndo_uninit().
Fortunately, we can unlock pn->all_ppp_mutex before calling
register_netdevice(). This lock protects pn->units_idr, which isn't
used in the device registration process.
However, keeping pn->all_ppp_mutex locked during device registration
did ensure that no device in transient state would be published in
pn->units_idr. In practice, unlocking it before calling
register_netdevice() doesn't change this property: ppp_unit_register()
is called with 'ppp_mutex' locked and all searches done in
pn->units_idr hold this lock too.

Set features function sets dev->features in order to keep track of which

This breaks the logic in __netdev_update_features which assumes that
dev->features is not changed on success and checks for diffs between

because of the driver override).

The link state and exception interrupts may be masked when we probe.
The firmware should in theory prevent sending (and automasking) those
interrupts if the device is disabled, but if my reading of the FW code
is correct there are firmwares out there with race conditions in this
area. The interrupt may also be masked if previous driver which used
the device was malfunctioning and we didn't load the FW (there is no
other good way to comprehensively reset the PF).
Note that FW unmasks the data interrupts by itself when vNIC is
enabled, such helpful operation is not performed for LSC/EXN interrupts.
Always unmask the auxiliary interrupts after request_irq(). On the
remove path add missing PCI write flush before free_irq().

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.

PS changes. This patch enables/disables PS mode according to
the new configuration.
Remove old behaviour enabling PS mode in a static way, this make
the device unusable when power save is enabled since device is
forced to PS regardless RX/TX traffic.

The flexcan_start_xmit() function compares the frame length with data
register length to write frame content into data[0] and data[1]
register. Data register length is 4 bytes and frame maximum length is 8
bytes.
Fix the check that compares frame length with 3. Because the register
length is 4.

The "set_bittiming" callback treats a positive return value as error!
For that reason "can_changelink()" will quit silently after setting
the bittiming values without processing ctrlmode, restart-ms, etc.

Picking up the patch from Serhey Popovych (commit 191cdb3822e5df6b3c8,
"veth: Be more robust on network device creation when no attributes").
When the peer name attribute is not provided the former implementation tries
to register the given device name twice ... which leads to -EEXIST.
If only one device name is given apply an automatic generated and valid name
for the peer.

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.

====================
Intel Wired LAN Driver Updates 2018-01-03
This series contains fixes for i40e and i40evf.
Amritha removes the UDP support for big buffer cloud filters since it is
not supported and having UDP enabled is a bug.
Alex fixes a bug in the __i40e_chk_linearize() which did not take into
account large (16K or larger) fragments that are split over 2 descriptors,
which could result in a transmit hang.
Jake fixes an issue where a devices own MAC address could be removed from
the unicast address list, so force a check on every address sync to ensure
removal does not happen.
Jiri Pirko fixes the return value when a filter configuration is not
supported, do not return "invalid" but return "not supported" so that
the core can react correctly.
