The watchdog task incorrectly changes the state to __IAVF_RESETTING,
instead of letting the reset task take care of that. This was already
resolved by commit 22c8fd71d3 ("iavf: do not override the adapter
state in the watchdog task") but the problem was reintroduced by the
recent code refactoring in commit 45eebd6299 ("iavf: Refactor iavf
state machine tracking").

We have two io-wq creation paths:
- On queue enqueue
- When a worker goes to sleep
The latter invokes worker creation with the wqe->lock held, but that can
run into problems if we end up exiting and need to cancel the queued work.

Recently, a patch has been submitted to "fix" the refcounting for a DT
node in of_mdiobus_link_mdiodev(). This is not a leaked refcount. The
refcount is passed to the new device.
Sadly, coccicheck identifies this location as a leaked refcount, which
means we're likely to keep getting patches to "fix" this. However,
fixing this will cause breakage. Add a comment to state that the lack
of of_node_put() here is intentional.

Commit 64d47d50be ("net: dsa: mv88e6xxx: configure interface settings

mv88e6xxx_mac_config(), where the link is forced down, and left it only
in mv88e6xxx_mac_link_up(), by which time link is unforced.
It seems that (at least on 88E6190) when changing cmode to 2500base-x,
if the link is not forced down, but the speed or duplex are still
forced, the forcing of new settings for speed & duplex doesn't take in
mv88e6xxx_mac_link_up().
Fix this by unforcing speed & duplex in mv88e6xxx_mac_link_down().

When listening for notifications through netlink of a new interface being
registered, sporadically, it is possible for the MAC to be read as zero.
The zero MAC address lasts a short period of time and then switches to a
valid random MAC address.
This causes problems for netd in Android, which assumes that the interface
is malfunctioning and will not use it.
In the good case we get this log:
InterfaceController::getCfg() ifName usb0
hwAddr 92:a8:f0:73:79:5b ipv4Addr 0.0.0.0 flags 0x1002
In the error case we get these logs:
InterfaceController::getCfg() ifName usb0
hwAddr 00:00:00:00:00:00 ipv4Addr 0.0.0.0 flags 0x1002
netd : interfaceGetCfg("usb0")
netd : interfaceSetCfg() -> ServiceSpecificException
(99, "[Cannot assign requested address] : ioctl() failed")
The reason for the issue is the order in which the interface is setup,
it is first registered through register_netdev() and after the MAC
address is set.
Fixed by first setting the MAC address of the net_device and after that
calling register_netdev().

USB3 Command Verifier (USB3CV) is the official tool for
USB3 Hub and Device Framework testing.
A high-speed capable device that has different device information
for full-speed and high-speed must have a Device Qualifier Descriptor.
This patch is to support device qualifier to pass

Introduces the Xen pvUSB frontend. With pvUSB it is possible for a Xen
domU to communicate with a USB device assigned to that domU. The
communication is all done via the pvUSB backend in a driver domain
(usually Dom0) which is owner of the physical device.
The pvUSB frontend is a USB hcd for a virtual USB host connector.
The code is taken from the pvUSB implementation in Xen done by Fujitsu
based on Linux kernel 2.6.18.
Changes from the original version are:
- port to upstream kernel
- put all code in just one source file
- move module to appropriate location in kernel tree
- adapt to Linux style guide
- minor code modifications to increase readability

Add the definition of pvUSB protocol used between the pvUSB frontend in
a Xen domU and the pvUSB backend in a Xen driver domain (usually Dom0).
This header was originally provided by Fujitsu for Xen based on Linux
2.6.18.
Changes are:
- adapt to Linux kernel style guide
- use Xen namespace
- add lots of comments
- don't use kernel internal defines

Synopsys introduced a new enhancement to DWC_usb32 called Multi-Stream
Transfer (MST) to improve bulk streams performance for SuperSpeed and
SuperSpeed Plus. This enhancement allows the controller to look ahead
and process multiple bulk streams.
Previously, to initiate a bulk stream transfer, the driver has to issue
Start Transfer command and wait for the stream to complete before
initiating a new stream. As a result, the controller does not process
TRBs beyond a single stream. With the enhancement, as long as there are
new requests, the dwc3 driver can keep preparing new TRBs and the
controller can keep caching and processing them without waiting for the
transfer completion.
The programming flow is similar to regular bulk endpoint with a few
additional rules:
1) Chained TRBs of the same stream must have a matching stream ID
2) The last TRB of a stream must have CHN=0
3) All the TRBs with LST=0 must have CSP=1
Depends on the application and usage, internal tests show significant
performance improvement in UASP transfers with this enhancement.

Using cluster topology on hybrid CPUs, e.g. Alder Lake, biases the
scheduler towards the ATOM cluster as that has more total capacity.
Use selection based on CPU priority instead.

Pull scheduler fix from Thomas Gleixner:
"A single fix for the x86 scheduler topology:
Using cluster topology on hybrid CPUs, e.g. Alder Lake, biases the
scheduler towards the ATOM cluster as that has more total capacity.
Use selection based on CPU priority instead"
