The phrase "Counter Count function" is verbose and unintentionally
implies that function is a Count extension. This patch adjusts the
Counter subsystem code to use the more direct "Counter function" phrase
to make the intent of this code clearer.

Only a select set of modes (function, action, etc.) are valid for a
given device configuration. This patch ensures that invalid modes result
in a return -EINVAL. Such a situation should never occur in reality, but
it's good to define a default switch case for the sake of making the

Reading/writing 4 bytes should be fast enough even on a slow bus, therefore
pci_vpd_wait() doesn't have to be interruptible. Making it uninterruptible
allows to simplify the code.
In addition make VPD writes uninterruptible in general. It's about vital
data, and allowing writes to be interruptible may leave the VPD in an
inconsistent state.

vpd->len is initialized to PCI_VPD_MAX_SIZE, and if a quirk is used to set
a specific VPD size, then pci_vpd_set_size() sets vpd->valid, resulting in
pci_vpd_size() not being called. Therefore we can remove the old_size
argument. Note that we don't have to check off < PCI_VPD_MAX_SIZE because
that's implicitly done by pci_read_vpd().

Previously, if we found any error in the VPD, we returned size 0, which
prevents access to all of VPD. But there may be valid resources in VPD
before the error, and there's no reason to prevent access to those.
"off" covers only VPD resources known to have valid header tags. In case
of error, return "off" (which may be zero if we haven't found any valid
header tags at all).

VPD consists of a series of Small and Large Resources. Computing the size
of VPD requires only the length of each, which is specified in the generic
tag of each resource. We only expect to see ID_STRING, RO_DATA, and
RW_DATA in VPD, but it's not a problem if it contains other resource types
because all we care about is the size.
Drop the validity checking of Large Resource items.

In situations were the developer screws up by e.g. not giving the OSM
nodes unique identifiers the interconnect framework might mix up nodes
between the OSM L3 provider and e.g. the RPMh provider.
The resulting callstack contains "qcom_icc_set", which is not unique to
the OSM L3 provider driver. Once the faulting qcom_icc_set() is
identified it's further confusing that "qcom_icc_node" is different
between the different drivers.
To avoid this confusion, rename the node struct and the setter in the
OSM L3 driver to include "osm_l3" in their names.

In some circumstances, such as with bridging, it's possible that the
stack will add the device's own MAC address to its unicast address list.
If, later, the stack deletes this address, the driver will receive a
request to remove this address.
The driver stores its current MAC address as part of the VSI MAC filter
list instead of separately. So, this causes a problem when the device's
MAC address is deleted unexpectedly, which results in traffic failure in
some cases.
The following configuration steps will reproduce the previously
mentioned problem:
> ip link set eth0 up
> ip link add dev br0 type bridge
> ip link set br0 up
> ip addr flush dev eth0
> ip link set eth0 master br0
> echo 1 > /sys/class/net/br0/bridge/vlan_filtering
> modprobe -r veth
> modprobe -r bridge
> ip addr add 192.168.1.100/24 dev eth0
The following ping command fails due to the netdev->dev_addr being
deleted when removing the bridge module.
> ping <link partner>
Fix this by making sure to not delete the netdev->dev_addr during MAC
address sync. After fixing this issue it was noticed that the
netdev_warn() in .set_mac was overly verbose, so make it at
netdev_dbg().
Also, there is a possibility of a race condition between .set_mac and
.set_rx_mode. Fix this by calling netif_addr_lock_bh() and
netif_addr_unlock_bh() on the device's netdev when the netdev->dev_addr
is going to be updated in .set_mac.

When VFs are setup and torn down in quick succession, it is possible
that a VF is torn down by the PF while the VF's virtchnl requests are
still in the PF's mailbox ring. Processing the VF's virtchnl request

this by adding a check to stop processing virtchnl requests when VF

The userspace utility "driverctl" can be used to change/override the
system's default driver choices. This is useful in some situations
(buggy driver, old driver missing a device ID, trying a workaround,
etc.) where the user needs to load a different driver.
However, this is also prone to user error, where a driver is mapped
to a device it's not designed to drive. For example, if the ice driver
is mapped to driver iavf devices, the ice driver crashes.
Add a check to return an error if the ice driver is being used to

All kernel devlink implementations call to devlink_alloc() during
initialization routine for specific device which is used later as
a parent device for devlink_register().
Such late device assignment causes to the situation which requires us to
call to device_register() before setting other parameters, but that call
opens devlink to the world and makes accessible for the netlink users.
Any attempt to move devlink_register() to be the last call generates the
following error due to access to the devlink->dev pointer.
[ 8.758862] devlink_nl_param_fill+0x2e8/0xe50
[ 8.760305] devlink_param_notify+0x6d/0x180
[ 8.760435] __devlink_params_register+0x2f1/0x670
[ 8.760558] devlink_params_register+0x1e/0x20
The simple change of API to set devlink device in the devlink_alloc()
instead of devlink_register() fixes all this above and ensures that
prior to call to devlink_register() everything already set.

The driver allocates the spinlock but not initialize it.
Use spin_lock_init() on it to initialize it correctly.

The CPSW switchdev driver inherited fix from commit 9421c9015047 ("net:
ethernet: ti: cpsw: fix min eth packet size") which changes min TX packet
size to 64bytes (VLAN_ETH_ZLEN, excluding ETH_FCS). It was done to fix HW
packed drop issue when packets are sent from Host to the port with PVID and
un-tagging enabled. Unfortunately this breaks some other non-switch
specific use-cases, like:
- [1] CPSW port as DSA CPU port with DSA-tag applied at the end of the
packet
- [2] Some industrial protocols, which expects min TX packet size 60Bytes
(excluding FCS).
Fix it by configuring min TX packet size depending on driver mode
- 60Bytes (ETH_ZLEN) for multi mac (dual-mac) mode
- 64Bytes (VLAN_ETH_ZLEN) for switch mode
and update it during driver mode change and annotate with
READ_ONCE()/WRITE_ONCE() as it can be read by napi while writing.

There was an "unknown" firmware variant turning up in the wild
causing problems in the clock driver. Add this missing variant
and clarify that varian 11 and 15 are Samsung variants, as this
is now very well known from released products.
