There was a sort of rush surrounding commit 88c0a6b503 ("net: create a
netdev notifier for DSA to reject PTP on DSA master"), due to a desire
to convert DSA's attempt to deny TX timestamping on a DSA master to
something that doesn't block the kernel-wide API conversion from
ndo_eth_ioctl() to ndo_hwtstamp_set().
What was required was a mechanism that did not depend on ndo_eth_ioctl(),
and what was provided was a mechanism that did not depend on
ndo_eth_ioctl(), while at the same time introducing something that
wasn't absolutely necessary - a new netdev notifier.
There have been objections from Jakub Kicinski that using notifiers in
general when they are not absolutely necessary creates complications to
the control flow and difficulties to maintainers who look at the code.
So there is a desire to not use notifiers.
In addition to that, the notifier chain gets called even if there is no
DSA in the system and no one is interested in applying any restriction.
Take the model of udp_tunnel_nic_ops and introduce a stub mechanism,
through which net/core/dev_ioctl.c can call into DSA even when
CONFIG_NET_DSA=m.
Compared to the code that existed prior to the notifier conversion, aka
what was added in commits:
- 4cfab35667 ("net: dsa: Add wrappers for overloaded ndo_ops")
- 3369afba1e ("net: Call into DSA netdevice_ops wrappers")
this is different because we are not overloading any struct
net_device_ops of the DSA master anymore, but rather, we are exposing a
rather specific functionality which is orthogonal to which API is used
to enable it - ndo_eth_ioctl() or ndo_hwtstamp_set().
Also, what is similar is that both approaches use function pointers to
get from built-in code to DSA.
There is no point in replicating the function pointers towards
__dsa_master_hwtstamp_validate() once for every CPU port (dev->dsa_ptr).
Instead, it is sufficient to introduce a singleton struct dsa_stubs,
built into the kernel, which contains a single function pointer to
__dsa_master_hwtstamp_validate().
I find this approach preferable to what we had originally, because
dev->dsa_ptr->netdev_ops->ndo_do_ioctl() used to require going through
struct dsa_port (dev->dsa_ptr), and so, this was incompatible with any
attempts to add any data encapsulation and hide DSA data structures from
the outside world.

Always return struct anarion_gmac * from anarion_config_dt().
In the case where ctl_block was an error pointer it was being
returned directly. Which sparse flags as follows:
.../dwmac-anarion.c:73:24: warning: incorrect type in return expression (different address spaces)
.../dwmac-anarion.c:73:24: expected struct anarion_gmac *
.../dwmac-anarion.c:73:24: got void [noderef] __iomem *[assigned] ctl_block
Avoid this by converting the error pointer to an error.
And then reversing the conversion.
As a side effect, the error can be used for logging purposes,
subjectively, leading to a minor cleanup.
No functional change intended.

Use __iomem annotation the register base: the ctl_block field of struct
anarion_gmac. I believe this is the normal practice for such variables.
By doing so some casting is avoided.
And sparse no longer reports:

Add support for J784S4 CPSW9G
This series adds a new compatible to am65-cpsw driver for the CPSW9G
instance of the CPSW Ethernet Switch on TI's J784S4 SoC which has 8
external ports and 1 internal host port.
The CPSW9G instance supports QSGMII and USXGMII modes for which driver
support is added.
Additionally, the interface mode specific configurations are moved to the
am65_cpsw_nuss_mac_config() callback. Also, a TODO comment is added for
verifying whether in-band mode is necessary for 10 Mbps RGMII mode.
NOTE:
I have verified that the mac_config() operations are preserved across
link up and link down events for SGMII and USXGMII mode with the new

Running this test makes little sense if the enabled l3_stats are not
actually reported as "used". This can signify a failure of a driver to
install the necessary counters, or simply lack of support for enabling
in-HW counters on a given netdevice. It is generally impossible to tell
from the outside which it is. But more likely than not, if somebody is
running this on veth pairs, they do not intend to actually test that a
certain piece of HW can install in-HW counters for the veth. It is more
likely they are e.g. running the test by mistake.
Therefore detect that the counter has not been actually installed. In that
case, if the netdevice is one end of a veth pair, SKIP. Otherwise FAIL.

`dev_port` is used to differentiate devices that instantiate from
the same function, which is the case in most of NFP NICs.
In some customized scenario, `dev_port` is used to rename netdev
instead of `phys_port_name`. Example rules using `dev_port`:
SUBSYSTEM=="net", ACTION=="add", KERNELS=="0000:e1:00.0", ATTR{dev_port}=="0", NAME:="ens8np0"
SUBSYSTEM=="net", ACTION=="add", KERNELS=="0000:e1:00.0", ATTR{dev_port}=="1", NAME:="ens8np1"
To take port split case into account, here we initialize `dev_port`
according to the port sequence in eth_table from management firmware
instead of using port label id directly. And management firmware
makes sure that port sequence matches its label id.

net: dsa: microchip: ksz8: Enhance static MAC table operations and error handling
This patch series improves the Microchip ksz8 driver by refactoring
static MAC table operations for code reuse, implementing add/del_fdb
functions, and making better use of error values in
ksz8_r_sta_mac_table() and ksz8_w_sta_mac_table(). The changes aim to
provide a more robust and maintainable driver with improved error

ConnectX-7 devices don't have ability to send TX hard/soft limits
events. As a possible workaround, let's rely on existing infrastructure
and use periodic check of cached flow counter. In these periodic checks,
we call to xfrm_state_check_expire() to check and mark state accordingly.
