Currently, we get icmp6hdr via function icmp6_hdr(), which needs the skb
transport header to be set first. But there is no rule to ask driver set
transport header before netif_receive_skb() and bond_handle_frame(). So
we will not able to get correct icmp6hdr on some drivers.
Fix this by using skb_header_pointer to get the IPv6 and ICMPV6 headers.

Setting of the port flag `NFP_PORT_CHANGED`, introduced
to ensure the correct reading of EEPROM data, causes a
fatal kernel NULL pointer dereference in cases where
the target netdev type cannot be determined.
Add validation of port struct pointer before attempting
to set the `NFP_PORT_CHANGED` flag. Return that operation
is not supported if the netdev type cannot be determined.

The error is reflected in that it shows wrong splittable status of
port when executing "devlink port show".
The reason which leads the error is that the assigned operation of
splittable is just a simple negation operation of split and it does
not consider port lanes quantity. A splittable port should have
several lanes that can be split(lanes quantity > 1).
If without the judgement, it will show wrong message for some
firmware, such as 2x25G, 2x10G.

As comment of pci_get_domain_bus_and_slot() says, it returns
a pci device with refcount increment, when finish using it,
the caller must decrement the reference count by calling
pci_dev_put().
In pch_gbe_probe(), pci_get_domain_bus_and_slot() is called,
so in error path in probe() and remove() function, pci_dev_put()
should be called to avoid refcount leak. Compile tested only.

Fix a deadlock introduced by commit
974578017fc1 ("iavf: Add waiting so the port is initialized in remove")
due to race condition between iavf_shutdown and iavf_remove, where
iavf_remove stucks forever in while loop since iavf_shutdown already
set __IAVF_REMOVE adapter state.
Fix this by checking if the __IAVF_IN_REMOVE_TASK has already been
set and return if so.

IAVF_FLAG_INITIAL_MAC_SET prevents waiting on iavf_is_mac_set_handled()

After commit aa626da947e9 ("iavf: Detach device during reset task")
the device is detached during reset task and re-attached at its end.
The problem occurs when reset task fails because Tx queues are
restarted during device re-attach and this leads later to a crash.
To resolve this issue properly close the net device in cause of
failure in reset task to avoid restarting of tx queues at the end.
Also replace the hacky manipulation with IFF_UP flag by device close
that clears properly both IFF_UP and __LINK_STATE_START flags.
In these case iavf_close() does not do anything because the adapter
state is already __IAVF_DOWN.
Reproducer:
1) Run some Tx traffic (e.g. iperf3) over iavf interface
2) Set VF trusted / untrusted in loop
[root@host ~]# cat repro.sh
PF=enp65s0f0

Recent commit aa626da947e9 ("iavf: Detach device during reset task")
removed netif_tx_stop_all_queues() with an assumption that Tx queues
are already stopped by netif_device_detach() in the beginning of
reset task. This assumption is incorrect because during reset
task a potential link event can start Tx queues again.
Revert this change to fix this issue.

2. Switch MTU of this interface in a loop

pch_gbe_tx_queue() sends data successfully or not, so pch_gbe_tx_queue()

You'd think people know that the internal 100BASE-TX PHY on the SJA1110
responds only to clause 22 MDIO transactions, but they don't :)
When a clause 45 transaction is attempted, sja1105_base_tx_mdio_read()
and sja1105_base_tx_mdio_write() don't expect "reg" to contain bit 30
set (MII_ADDR_C45) and pack this value into the SPI transaction buffer.
But the field in the SPI buffer has a width smaller than 30 bits, so we
see this confusing message from the packing() API rather than a proper
rejection of C45 transactions:
Call trace:

Dan Carpenter reported that Smatch found an instance where a pointer
which had previously been assumed could be null (as indicated by a
null check) was later dereferenced without a similar check.
In practice this doesn't lead to a problem because currently the
pointers used are all non-null. Nevertheless this patch addresses
the reported problem.
In addition, I spotted another bug that arose in the same commit.
When the command to initialize a routing table memory region was
added, the number of entries computed for the non-hashed table
was wrong (it ended up being a Boolean rather than the count
intended). This bug is fixed here as well.

Introduce a new way of specifying how the GSI firmware gets loaded
for IPA. Currently, this is indicated by the presence or absence of
the Boolean "modem-init" Device Tree property. The new property
must have a value--either "self" or "modem"--which indicates whether
the AP or modem is the GSI firmware loader, respectively.
For legacy systems, the new property will not exist, and the
"modem-init" property will be used. For newer systems, the
"qcom,gsi-loader" property *must* exist, and must have one of the
two prescribed values. It is an error to have both properties
defined, and it is an error for the new property to have an
unrecognized value.

There is a need to support modification of Tx scheduler tree, in the
ice driver. This will allow user to control Tx settings of each node in
the internal hierarchy of nodes. As a result user will be able to use
Hierarchy QoS implemented entirely in the hardware.
This patch implemenents devlink-rate API. It also exports initial
default hierarchy. It's mostly dictated by the fact that the tree
can't be removed entirely, all we can do is enable the user to modify
it. For example root node shouldn't ever be removed, also nodes that
have children are off-limits.
Example initial tree with 2 VF's:
[root@fedora ~]# devlink port function rate show
pci/0000:4b:00.0/node_27: type node parent node_26
pci/0000:4b:00.0/node_26: type node parent node_0

pci/0000:4b:00.0/node_15: type node parent node_0

pci/0000:4b:00.0/node_1: type node parent node_0
pci/0000:4b:00.0/node_0: type node
pci/0000:4b:00.0/1: type leaf parent node_27
pci/0000:4b:00.0/2: type leaf parent node_27
Let me visualize part of the tree:
+---------+
| node_0 |
+---------+
|
+----v----+
| node_26 |
+----+----+
|
+----v----+
| node_27 |
+----+----+
|
|-----------------|
+----v----+ +----v----+
| VF 1 | | VF 2 |
+----+----+ +----+----+
So at this point there is a couple things that can be done.
For example we could only assign parameters to VF's.
[root@fedora ~]# devlink port function rate set pci/0000:4b:00.0/1 \
tx_max 5Gbps
This would cap the VF 1 BW to 5Gbps.
But let's say you would like to create a completely new branch.
This can be done like this:
[root@fedora ~]# devlink port function rate add \
pci/0000:4b:00.0/node_custom parent node_0
[root@fedora ~]# devlink port function rate add \
pci/0000:4b:00.0/node_custom_1 parent node_custom
[root@fedora ~]# devlink port function rate set \
pci/0000:4b:00.0/1 parent node_custom_1
This creates a completely new branch and reassigns VF 1 to it.
A number of parameters is supported per each node: tx_max, tx_share,
tx_priority and tx_weight.

Currently the driver is able to create leaf nodes for the devlink-rate,
but is unable to set parent for them. This wasn't as issue before the
possibility to export hierarchy from the driver. After adding the export
feature, in order for the driver to supply correct hierarchy, it's
necessary for it to be able to supply a parent name to
devl_rate_leaf_create().
Introduce a new parameter 'parent_name' in devl_rate_leaf_create().

Many of the drivers which implement ethtool_ops::get_drvinfo() will
prints the .driver, .version or .bus_info of struct ethtool_drvinfo.
To have a glance of current state, do:
$ git grep -W "get_drvinfo(struct"
Printing in those three fields is useless because:
- since [1], the driver version should be the kernel version (at
least for upstream drivers). Arguably, out of tree drivers might
still want to set a custom version, but out of tree is not our
focus.
- since [2], the core is able to provide default values for .driver
and .bus_info.
In summary, drivers may provide .fw_version and .erom_version, the
rest is expected to be done by the core.
In struct ethtool_ops doc from linux/ethtool: rephrase field
get_drvinfo() doc to discourage developers from implementing this
callback.
In struct ethtool_drvinfo doc from uapi/linux/ethtool.h: remove the
paragraph mentioning what drivers should do. Rationale: no need to
repeat what is already written in struct ethtool_ops doc. But add a
note that .fw_version and .erom_version are driver defined.
Also update the dummy driver and simply remove the callback in order
not to confuse the newcomers: most of the drivers will not need this
callback function any more.

The mlxsw adjfine implementation in the spectrum_ptp.c file converts
scaled_ppm into ppb before updating a cyclecounter multiplier using the
standard "base * ppb / 1billion" calculation.
This can be re-written to use adjust_by_scaled_ppm, directly using the
scaled parts per million and reducing the amount of code required to
express this calculation.
We still calculate the parts per billion for passing into
mlxsw_sp_ptp_phc_adjfreq because this function requires the input to be in
parts per billion.

'ret' is not updated after several function calls in rtw89_wow_enable().
This prevent error handling from working.
Add the missing assignments.

When built with Control Flow Integrity, function prototypes between
caller and function declaration must match. These mismatches are visible
at compile time with the new -Wcast-function-type-strict in Clang[1].
Fix a total of 32 warnings like these:
../drivers/net/wireless/cisco/airo.c:7570:2: warning: cast from 'int (*)(struct net_device *, struct iw_request_info *, void *, char *)' to 'iw_handler' (aka 'int (*)(struct net_device *, struct iw_request_info *, union iwreq_data *, char *)') converts to incompatible function type [-Wcast-function-type-strict]
(iw_handler) airo_config_commit, /* SIOCSIWCOMMIT */
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The airo Wireless Extension handler callbacks (iw_handler) use a
union for the data argument. Actually use the union and perform explicit
member selection in the function body instead of having a function
prototype mismatch. There are no resulting binary differences
before/after changes.
These changes were made partly manually and partly with the help of
Coccinelle.
