net: stmmac: anarion: cleanups
A series of cleanups to the anarion glue driver.
Clean up anarion_config_dt() error handling, printing a human readable
error rather than the numeric errno, and use ERR_CAST().
Using a switch statement with incorrect "fallthrough;" for RGMII vs
non-RGMII is unnecessary when we have phy_interface_mode_is_rgmii().
Convert to use the helper.
Use stmmac_pltfr_probe() rahter than open-coding the call to the
init function (which stmmac_pltfr_probe() will do for us.)
Finally, convert to use devm_stmmac_pltfr_probe() which allows the
removal of the .remove initialiser in the driver structure.
Not tested on hardware.

====================
net: Introduce nlmsg_payload helper
In the current codebase, there are multiple instances where the
structure size is checked before assigning it to a Netlink message. This
check is crucial for ensuring that the structure is correctly mapped
onto the Netlink message, providing a layer of security.
To streamline this process, Jakub Kicinski suggested creating a helper
function, `nlmsg_payload`, which verifies if the structure fits within
the message. If it does, the function returns the data; otherwise, it
returns NULL. This approach simplifies the code and reduces redundancy.
This patchset introduces the `nlmsg_payload` helper and updates several
parts of the code to use it. Further updates will follow in subsequent
patchsets.

The parent commit adds this new counter, incremented when receiving a

Most of the time, it is then kept at 0, except when the PM limits cause
the receiver side to reject new MPJoin connections. This is the case in
the following tests:
- single subflow, limited by server
- multiple subflows, limited by server
- subflows limited by server w cookies
- userspace pm type rejects join
- userspace pm type prevents mp_prio
Simply set join_syn_rej=1 when checking the MPJoin counters for these

the real one from the Switch MIB. This can happen if the switch directly
forward packets between the ports or offload small packets like ARP
request. In such case, the kernel counter will desync compared to the
real one transmitted and received by the Switch.
To correctly provide the real info to the kernel, implement .get_stats64
that will directly read the current MIB counter from the switch

The RXB also supports pause frame stats counters which we are leaving
for a later patch.

This patch provides support for hardware queue stats and covers
packet errors for RX-DMA engine, RCQ drops and BDQ drops.
The packet errors are also aggregated with the `rx_errors` stats in the
`rtnl_link_stats` as well as with the `hw_drops` in the queue API.
The RCQ and BDQ drops are aggregated with `rx_over_errors` in the
`rtnl_link_stats` as well as with the `hw_drop_overruns` in the queue API.

This patch adds lock protection for the hardware statistics for fbnic.
The hardware statistics access via ndo_get_stats64 is not protected by
the rtnl_lock(). Since these stats can be accessed from different places
in the code such as service task, ethtool, Q-API, and net_device_ops, a
lock-less approach can lead to races.
Note that this patch is not a fix rather, just a prep for the subsequent
changes in this series.

Add a driver for the MDIO controller on the RTL9300 family of Ethernet
switches with integrated SoC. There are 4 physical SMI interfaces on the
RTL9300 however access is done using the switch ports. The driver takes
the MDIO bus hierarchy from the DTS and uses this to configure the
switch ports so they are associated with the correct PHY. This mapping
is also used when dealing with software requests from phylib.

Russell King says:
====================
net: stmmac: qcom-ethqos: simplifications
Remove unnecessary code from the qcom-ethqos glue driver.
Start by consistently using -> serdes_speed to set the speed of the
serdes PHY rather than sometimes using ->serdes_speed and sometimes
using ->speed.
This then allows the removal of ->speed in the second patch.
There is no need to set the maximum speed just because we're using
2500BASE-X - phylink already knows that 2500BASE-X can't support
faster speeds.
This then makes qcom_ethqos_speed_mode_2500() redundant as it's
setting the interface mode to the value that was determined in the
switch statement that already determined that the interface mode
had this value.
Not tested on hardware.
