mlxsw is using helpers to get / set fields in messages exchanged with
the device. It is possible that some fields are only set or only get.
This causes LLVM to emit warnings such as the following when building
with W=1 [1]:

drivers/net/ethernet/mellanox/mlxsw/core_acl_flex_actions.c:2022:1: warning: unused function 'mlxsw_afa_sampler_mirror_agent_get'

The fact that some fields are only set or only get is very much
intentional and not indicative of functions that need to be removed.

Therefore, annotate the item helpers with '__maybe_unused' to suppress
these warnings.

====================
net: introduce a function to check if a netdev name is in use

This was initially part of an RFC series[1] but has value on its own;
hence the standalone report. (It will also help in not having a series
too large).

From patch 1:

"""
__dev_get_by_name is currently used to either retrieve a net device
reference using its name or to check if a name is already used by a
registered net device (per ns). In the later case there is no need to
return a reference to a net device.

Introduce a new helper, netdev_name_in_use, to check if a name is
currently used by a registered net device without leaking a reference
the corresponding net device. This helper uses netdev_name_node_lookup
instead of __dev_get_by_name as we don't need the extra logic retrieving
a reference to the corresponding net device.
"""

Two uses[2] of __dev_get_by_name weren't converted to this new function,
as they are really looking for a net device, not only checking if a net
device name is in use. While checking one or the other currently has
the same result, that might change if the initial RFC series moves
forward. I'll convert them later depending on the outcome of the initial
series.

Thanks,
Antoine

net: enetc: add support for software TSO

This series adds support for driver level TSO in the enetc driver.

Ever since the ENETC MDIO erratum workaround is in place, the Tx path is
incurring a penalty (enetc_lock_mdio/enetc_unlock_mdio) for each skb to
be sent out. On top of this, ENETC does not support Tx checksum
offloading. This means that software TSO would help performance just by
the fact that one single mdio lock/unlock sequence would cover multiple
packets sent. On the other hand, checksum needs to be computed in
software since the controller cannot handle it.

This is why, beside using the usual tso_build_hdr()/tso_build_data()
this specific implementation also has to compute the checksum, both IP
and L4, for each resulted segment.

Even with that, the performance improvement of a TCP flow running on a
single A72@1.3GHz of the LS1028A SoC (2.5Gbit/s port) is the following:

before: 1.63 Gbits/sec
after:  2.34 Gbits/sec

Changes in v2:
 - declare NETIF_F_HW_CSUM instead of NETIF_F_IP_CSUM in 1/2
 - add support for TSO over IPv6 (NETIF_F_TSO6 and csum compute) in 2/2
====================

This patch adds support for driver level TSO in the enetc driver using
the TSO API.

Beside using the usual tso_build_hdr(), tso_build_data() this specific
implementation also has to compute the checksum, both IP and L4, for
each resulted segment. This is because the ENETC controller does not
support Tx checksum offload which is needed in order to take advantage
of TSO.

With the workaround for the ENETC MDIO erratum in place the Tx path of
the driver is forced to lock/unlock for each skb sent. This is why, even
though we are computing the checksum by hand we see the following
improvement in TCP termination on the LS1028A SoC, on a single A72 core
running at 1.3GHz:

before: 1.63 Gbits/sec

Patch #1 adds a new config option to determine if 'skip_sw' / 'skip_hw'
flags are used when installing tc filters. By default, it is not set
which means the flags are not used. 'skip_sw' is useful to ensure
traffic is forwarded by the hardware data path.

Due to deadlocks in the networking subsystem spotted 12 years ago[1],
a workaround was put in place[2] to avoid taking the rtnl lock when it
was not available and restarting the syscall (back to VFS, letting
userspace spin). The following construction is found a lot in the net
sysfs and sysctl code:

  if (!rtnl_trylock())
          return restart_syscall();

This can be problematic when multiple userspace threads use such
interfaces in a short period, making them to spin a lot. This happens
for example when adding and moving virtual interfaces: userspace
programs listening on events, such as systemd-udevd and NetworkManager,
do trigger actions reading files in sysfs. It gets worse when a lot of
virtual interfaces are created concurrently, say when creating
containers at boot time.

Returning early without hitting the above pattern when the syscall will
fail eventually does make things better. While it is not a fix for the
issue, it does ease things.

   - Regression fixes for missing CONFIG_FB and other options for
     several defconfigs

   - Several bug fixes for the newly added Microchip SAMA7 platform,
     mostly regarding power management

   - Missing SMP barriers to protect accesses to SCMI virtio device

   - Regression fixes for TI OMAP, including a boot-time hang on am335x.

   - Lots of bug fixes for NXP i.MX, mostly addressing incorrect
     settings in devicetree files, and one revert for broken suspend.

   - Fixes for ARM Juno/Vexpress devicetree files, addressing a couple
     of schema warnings.

   - Regression fixes for qualcomm SoC specific drivers and devicetree
     files, reverting an mdt_loader change and at least pastially
     reverting some of the 5.15 DTS changes, plus some minor bugfixes"

SCMI fixes for v5.15

A few fixes addressing:
- Kconfig dependency between VIRTIO and ARM_SCMI_PROTOCOL
- Link-time error with __exit annotation for virtio_scmi_exit
- Unnecessary nested irqsave/irqrestore spinlocks in virtio transport
- Missing SMP barriers to protect accesses to SCMI virtio device
