Convert more drivers following the groundwork laid in a recent

This set converts all the drivers outside of drivers/net/ethernet.
Only vmxnet3 them was checking unsupported parameters.
The aim is to merge this via the net-next tree so we can

tun: debug messages cleanup
While testing ethtool output for "strange" devices, I noticed confusing and
obviously incorrect message level information for a tun device and sent
a quick fix. The result of the upstream discussion was that tun driver
would rather deserve a more complex cleanup of the way it handles debug
messages.
The main problem is that all debugging statements and setting of message
level are controlled by TUN_DEBUG macro which is only defined if one edits
the source and rebuilds the module, otherwise all DBG1() and tun_debug()
statements do nothing.
This series drops the TUN_DEBUG switch and replaces custom tun_debug()
macro with standard netif_info() so that message level (mask) set and
displayed using ethtool works as expected. Some debugging messages are
dropped as they only notify about entering a function which can be done
easily using ftrace or kprobe.
Patch 1 is a trivial fix for compilation warning with W=1.

debug statements.
Also drop the tun_debug() statement informing about SIOCSIFHWADDR ioctl.
We can monitor these through rtnetlink and it makes little sense to log
address changes through ioctl but not changes through rtnetlink. Moreover,
this tun_debug() is called even if the actual address change fails which

PCI: Implement function to read Device Serial Number
Several drivers read the Device Serial Number from the PCIe extended
configuration space. Each of these drivers implements a similar approach to
finding the position and then extracting the 8 bytes of data.
Implement a new helper function, pci_get_dsn, which can be used to extract
this data into an 8 byte array.
Modify the bnxt_en, qedf, ice, ixgbe and nfp drivers to use this new
function.
The intent for this is to reduce duplicate code across the various drivers,
and make it easier to write future code that wants to read the DSN. In
particular the ice driver will be using the DSN as its serial number when
implementing the DEVLINK_CMD_INFO_GET.
The new implementation in v2 significantly simplifies some of the callers
which just want to print the value out in MSB order. By returning things as
a u64 in CPU Endian order, the "%016llX" printf format specifier can be used
to correctly format the value.
Per patch changes since v1
PCI: Introduce pci_get_dsn
* Update commit message based on feedback from Bjorn Helgaas
* Modify the function to return a u64 (zero on no capability)
* This new implementation ensures that the first dword is the lower 32

bnxt_en: Use pci_get_dsn()
* Use the u64 return value from pci_get_dsn()
* Copy it into the dsn[] array by using put_unaligned_le64
* Fix a pre-existing typo in the netdev_info error message
scsi: qedf: Use pci_get_dsn()
* Use the u64 return value from pci_get_dsn()
* simplify the snprintf to use "%016llX"
* remove the unused 'i' variable

Use the newly added pci_get_dsn() function for obtaining the 64-bit
Device Serial Number in the nfp6000_read_serial and
nfp_6000_get_interface functions.
pci_get_dsn() reports the Device Serial number as a u64 value created by
combining two pci_read_config_dword functions. The lower 16 bits
represent the device interface value, and the next 48 bits represent the
serial value. Use put_unaligned_be32 and put_unaligned_be16 to convert
the serial value portion into a Big Endian formatted serial u8 array.

The pci_get_dsn() function returns the DSN as a u64, correctly ordering
the upper and lower 32 bit dwords. Simplify the display code by using
%016llX to display the u64 DSN.
This should have equivalent behavior on both Little and Big Endian

On Little Endian systems, the least significant byte comes first, which
will be the least significant byte of the first dword, followed by the

On Big Endian systems, the most significant byte of the second dword
will come first. put_unaligned_le64 will perform a CPU_TO_LE64, which

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.

mlxsw: Offload FIFO
Petr says:
If an ETS or PRIO band contains an offloaded qdisc, it is possible to
obtain offloaded counters for that band. However, some of the bands will
likely simply contain the default invisible FIFO qdisc, which does not
present the counters.
To remedy this situation, make FIFO offloadable, and offload it by mlxsw
when below PRIO and ETS for the sole purpose of providing counters for the
bands that do not include other qdiscs.
- In patch #1, FIFO is extended to support offloading.
- Patches #2 and #3 restructure bits of mlxsw to facilitate
the offload logic.
- Patch #4 then implements the offload itself.
- Patch #5 changes the ETS selftest to use the new counters.

Currently the SW-datapath ETS selftests use "ip link" stats to obtain the
number of packets that went through a given band. mlxsw then uses ethtool
per-priority counters.
Instead, change both to use qdiscs. In SW datapath this is the obvious
choice, and now that mlxsw offloads FIFO, this should work on the offloaded
datapath as well. This has the effect of verifying that the FIFO offload
works.

There are two peculiarities about offloading FIFO:
- sometimes the qdisc has an unspecified handle (it is "invisible")
- it may be created before the qdisc that it will be a child of
These features make the offload a bit more tricky. The approach chosen in
this patch is to make note of all the FIFOs that needed to be rejected
because their parents were not known. Later when the parent is created,
they are offloaded
FIFO is only offloaded for its counters, queue length is ignored.

ethtool: consolidate parameter checking for irq coalescing
This set aims to simplify and unify the unsupported irq
coalescing parameter handling.
First patch adds a bitmask which drivers should fill in
in their ethtool_ops structs to declare which parameters
they support. Core will then ensure that driver callback
won't see any parameter outside of that set.
This allows us to save some LoC and make sure all drivers
respond the same to unsupported parameters.
If any parameter driver does not support is set to a value
other than 0 core will return -EINVAL. In the future we can
reject any present but unsupported netlink attribute, without
assuming 0 means unset. We can also add some prints or extack,
perhaps a'la Intel's current code.
I started converting the drivers alphabetically but then
realized that for the first set it's probably best to
address a representative mix of actively developed drivers.
According to my unreliable math there are roughly 69 drivers
in the tree which support some form of interrupt coalescing
settings via ethtool. Of these roughly 17 reject parameters
they don't support.
I hope drivers which ignore the parameters don't care, and
won't care about the slight change in behavior. Once all
drivers are converted we can make the checking mandatory.
I've only tested the e1000e and virtio patches, the rest builds.
v2: fix up ice and virtio conversions
v3: (patch 1)
- move the (temporary) check if driver defines types
