On Cavium ThunderX2 arm64 SoCs (formerly known as Broadcom Vulcan), the PCI
topology is slightly unusual. For a multi-node system, it looks like:
00:00.0 PCI bridge to [bus 01-1e]
01:0a.0 PCI-to-PCIe bridge to [bus 02-04]
02:00.0 PCIe Root Port bridge to [bus 03-04] (XLATE_ROOT)
03:00.0 PCIe Endpoint
pci_for_each_dma_alias() assumes IOMMU translation is done at the root of
the PCI hierarchy. It generates 03:00.0, 01:0a.0, and 00:00.0 as DMA
aliases for 03:00.0 because buses 01 and 00 are non-PCIe buses that don't
carry the Requester ID.
Because the ThunderX2 IOMMU is at 02:00.0, the Requester IDs 01:0a.0 and
00:00.0 are never valid for the endpoint. This quirk stops alias
generation at the XLATE_ROOT bridge so we won't generate 01:0a.0 or
00:00.0.
The current IOMMU code only maps the last alias (this is a separate bug in
itself). Prior to this quirk, we only created IOMMU mappings for the
invalid Requester ID 00:00:0, which never matched any DMA transactions.
With this quirk, we create IOMMU mappings for a valid Requester ID, which
fixes devices with no aliases but leaves devices with aliases still broken.
The last alias for the endpoint is also used by the ARM GICv3 MSI-X code.
Without this quirk, the GIC Interrupt Translation Tables are setup with the
invalid Requester ID, and the MSI-X generated by the device fails to be
translated and routed.

Recently, suspend/resume and WOL support are added into mvneta driver.
If we enable WOL, then we get some error as below on Marvell BG4CT
platforms during suspend:
[ 184.149723] dpm_run_callback(): mdio_bus_suspend+0x0/0x50 returns -16
[ 184.149727] PM: Device f7b62004.mdio-mi:00 failed to suspend: error -16
-16 means -EBUSY, phy_suspend() will return -EBUSY if it finds the
device has WOL enabled.
We fix this issue by properly setting the netdev's power.can_wakeup
and power.wakeup, i.e
1. in mvneta_mdio_probe(), call device_set_wakeup_capable() to set
power.can_wakeup if the phy support WOL.
2. in mvneta_ethtool_set_wol(), call device_set_wakeup_enable() to
set power.wakeup if WOL has been successfully enabled in phy.

The reason: phy_driver structure for KSZ9031 phy has no .probe() callback
defined. As result, struct phy_device *phydev->priv pointer will not be
initializes (null).
This issue will affect also following phys:
KSZ8795, KSZ886X, KSZ8873MLL, KSZ9031, KSZ9021, KSZ8061, KS8737
Fix it by:
- adding .probe() = kszphy_probe() callback to KSZ9031, KSZ9021
phys. The kszphy_probe() can be re-used as it doesn't do any phy specific
settings.
- removing statistic callbacks from other phys (KSZ8795, KSZ886X,
KSZ8873MLL, KSZ8061, KS8737) as they doesn't have corresponding
statistic counters.

phylib has some undesirable behaviour when forcing a link mode through
ethtool. phylib uses this code:
idx = phy_find_valid(phy_find_setting(phydev->speed, phydev->duplex),
features);
to find an index in the settings table. phy_find_setting() starts at
index 0, and scans upwards looking for an exact speed and duplex match.
When it doesn't find it, it returns MAX_NUM_SETTINGS - 1, which is
10baseT-Half duplex.
phy_find_valid() then scans from the point (and effectively only checks
one entry) before bailing out, returning MAX_NUM_SETTINGS - 1.
phy_sanitize_settings() then sets ->speed to SPEED_10 and ->duplex to
DUPLEX_HALF whether or not 10baseT-Half is supported or not. This goes
against all the comments against these functions, and 10baseT-Half may
not even be supported by the hardware.
Rework these functions, introducing a new method of scanning the table.
There are two modes of lookup that phylib wants: exact, and inexact.
- in exact mode, we return either an exact match or failure
- in inexact mode, we return an exact match if it exists, a match at
the highest speed that is not greater than the requested speed
(ignoring duplex), or failing that, the lowest supported speed, or
failure.
The biggest difference is that we always check whether the entry is
supported before further consideration, so all unsupported entries are
not considered as candidates.
This results in arguably saner behaviour, better matches the comments,
and is probably what users would expect.
This becomes important as ethernet speeds increase, PHYs exist which do
not support the 10Mbit speeds, and half-duplex is likely to become
obsolete - it's already not even an option on 10Gbit and faster links.

The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.
But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.

The I2C core always reports a MODALIAS of the form i2c:<foo> even if the
device was registered via OF, this means that exporting the OF device ID
table device aliases in the module is not needed. But in order to change
how the core reports modaliases to user-space, it's better to export it.

When running a disconnect torture test I noticed that sometimes we would

ending the same request twice. Turns out we were racing with
NBD_CLEAR_SOCK clearing the requests as well as the teardown of the

the sockets and make it so that we only ever run nbd_clear_que from the

The existing ioctl interface for configuring NBD devices is a bit
cumbersome and hard to extend. The other problem is we leave a
userspace app sitting in it's syscall until the device disconnects,
which is less than ideal.
This patch introduces a netlink interface for adding and disconnecting
nbd devices. This has the benefits of being easily extendable without
breaking older userspace applications, and allows us to configure a nbd
device without leaving a userspace app sitting waiting for the device to
disconnect.
With this interface we also gain the ability to configure more devices
than are preallocated at insmod time. We also have gained the ability
to not specify a particular device and be provided one for us so that
userspace doesn't need to find a free device to configure.

In order to properly refcount the various aspects of a NBD device we
need to separate out the configuration elements of the nbd device. The
configuration of a NBD device has a different lifetime from the actual
device, so it doesn't make sense to bundle these two concepts. Add a
config_refs to keep track of the configuration structure, that way we
can be sure that we never access it when we've torn down the device.
Add a new nbd_config structure to hold all of the transient
configuration information. Finally create this when we open the device
so that it is in place when we start to configure the device. This has
a nice side-effect of fixing a long standing problem where you could end
up with a half-configured nbd device that needed to be "disconnected" in
order to be usable again. Now once we close our device the
configuration will be discarded.

Currently if we have multiple connections and one of them goes down we will tear
down the whole device. However there's no reason we need to do this as we
could have other connections that are working fine. Deal with this by keeping
track of the state of the different connections, and if we lose one we mark it
as dead and send all IO destined for that socket to one of the other healthy
sockets. Any outstanding requests that were on the dead socket will timeout and
be re-submitted properly.

Currently the driver support only ethernet eswitch, and we want to
protect downstream IPoIB netdev from trying to access it in IB link.

In order to have different RX handler per profile, fix and refactor the
current code to take the rx handler directly from the netdevice profile
rather than computing it on runtime as it was done with the switchdev
mode representor rx handler.
This will also remove the current wrong assumption in mlx5e_alloc_rq
code that mlx5e_priv->ppriv is of the type vport_rep.

Implement mlx5e's IPoIB SKB transmit using the helper functions provided
by mlx5e ethernet tx flow, the only difference in the code between
mlx5e_xmit and mlx5i_xmit is that IPoIB has some extra fields to fill
(UD datagram segment) in the TX descriptor (WQE) and it doesn't need to
have any vlan handling.

Create IPoIB underlay QP needed by the IPoIB netdevice profile for RSS
and TX HW context to perform on IPoIB traffic.
Reset the underlay QP on dev_uninit ndo to stop IPoIB traffic going
through this QP when the ULP IPoIB decides to cleanup.
Implement attach/detach mcast RDMA netdev callbacks for later RDMA
netdev use.

Modify mlx5e tis creation function to accept underlay qp number, which
will be needed by IPoIB.
Implement mlx5i (IPoIB) tx init/cleanup netdevice profile flows to
create one TIS with the IPoIB underlay qp, for IPoIB TX SQs.
