Add a new region type that allows us to dump the PCI config space.
This is mostly the same as dumping a memory region, but reading from
the device's config space instead.
In order to make this generic and independent of the trans type, we
make a function called iwl_dump_ini_config_iter() that calls a new op
in the transport to read its config space.

So far we set phydev->suspended to true in phy_suspend() even if the
PHY driver doesn't implement the suspend callback. This applies
accordingly for the resume path. The current behavior doesn't cause
any issue I'd be aware of, but it's not logical and misleading,
especially considering the description of the flag:
"suspended: Set to true if this phy has been suspended successfully"

and edacb098ea9c ("net: ks8851-ml: Fix 16-bit data access"), because it
turns out these were only necessary due to buggy hardware. This patch adds
a check for such a buggy hardware to prevent any such mistakes again.
While working further on the KS8851 driver, it came to light that the
KS8851-16MLL is capable of switching bus endianness by a hardware strap,
EESK pin. If this strap is incorrect, the IO accesses require such endian
swapping as is being reverted by this patch. Such swapping also impacts
the performance significantly.
Hence, in addition to removing it, detect that the hardware is broken,
report to user, and fail to bind with such hardware.

This patch makes real_dev_feature propagation by MACSec offloaded device.
Issue description:
real_dev features are disabled upon macsec creation.
Root cause:
Features limitation (specific to SW MACSec limitation) is being applied
to HW offloaded case as well.
This causes 'set_features' request on the real_dev with reduced feature
set due to chain propagation.
Proposed solution:
Report real_dev features when HW offloading is enabled.
NB! MACSec offloaded device does not propagate VLAN offload features at
the moment. This can potentially be added later on as a separate patch.
Note: this patch requires HW offloading to be enabled by default in order
to function properly.

The TI AM65x/J721E SoCs Gigabit Ethernet Switch subsystem (CPSW2G NUSS) has
two ports - One Ethernet port (port 1) with selectable RGMII and RMII
interfaces and an internal Communications Port Programming Interface (CPPI)
port (Host port 0) and with ALE in between. It also contains
- Management Data Input/Output (MDIO) interface for physical layer device
(PHY) management;
- Updated Address Lookup Engine (ALE) module;
- (TBD) New version of Common platform time sync (CPTS) module.
On the TI am65x/J721E SoCs CPSW NUSS Ethernet subsystem into device MCU
domain named MCU_CPSW0.
Host Port 0 CPPI Packet Streaming Interface interface supports 8 TX
channels and one RX channels operating by TI am654 NAVSS Unified DMA
Peripheral Root Complex (UDMA-P) controller.
Introduced driver provides standard Linux net_device to user space and supports:
- ifconfig up/down
- MAC address configuration
- ethtool operation:
--driver
--change
--register-dump
--negotiate phy
--statistics
--set-eee phy
--show-ring
--show-channels
--set-channels
- net_device ioctl mii-control
- promisc mode
- rx checksum offload for non-fragmented IPv4/IPv6 TCP/UDP packets.
The CPSW NUSS can verify IPv4/IPv6 TCP/UDP packets checksum and fills
csum information for each packet in psdata[2] word:
- BIT(16) CHECKSUM_ERROR - indicates csum error
- BIT(17) FRAGMENT - indicates fragmented packet
- BIT(18) TCP_UDP_N - Indicates TCP packet was detected
- BIT(19) IPV6_VALID, BIT(20) IPV4_VALID - indicates IPv6/IPv4 packet
- BIT(15, 0) CHECKSUM_ADD - This is the value that was summed
during the checksum computation. This value is FFFFh for non fragmented
IPV4/6 UDP/TCP packets with no checksum error.
RX csum offload can be disabled:
ethtool -K <dev> rx-checksum on|off
- tx checksum offload support for IPv4/IPv6 TCP/UDP packets (J721E only).
TX csum HW offload can be enabled/disabled:
ethtool -K <dev> tx-checksum-ip-generic on|off
- multiq and switch between round robin/prio modes for cppi tx queues by
using Netdev private flag "p0-rx-ptype-rrobin" to switch between
Round Robin and Fixed priority modes:
# ethtool --show-priv-flags eth0
Private flags for eth0:
p0-rx-ptype-rrobin: on
# ethtool --set-priv-flags eth0 p0-rx-ptype-rrobin off
Number of TX DMA channels can be changed using "ethtool -L eth0 tx <N>".
- GRO support: the napi_gro_receive() and napi_complete_done() are used.

The new CPSW ALE version, available on TI K3 AM654/J721E SoCs family,
allows to switch any external port to MAC only mode. When MAC only mode
enabled this port be treated like a MAC port for the host. All traffic
received is only sent to the host. The host must direct traffic to this
port as the lookup engine will not send traffic to the ports with the
p0_maconly bit set and the p0_no_learn also set. If p0_maconly bit is set
and the p0_no_learn is not set, the host can send non-directed packets that
can be sent to the destination of a MacOnly port. It is also possible that
The host can broadcast to all ports including MacOnly ports in this mode.
This patch add ALE supprt for MAC only mode.

On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS the unregistered multicast
packets are still can be received with promisc and allmulti disabled.
This happens, because ALE VLAN entries on these SoCs do not contain port
masks for reg/unreg mcast packets, but instead store indexes of
ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for
reg/unreg mcast packets.
ALE VLAN entry:UNREG_MCAST_FLOOD_INDEX -> ALE_VLAN_MASK_MUXx
ALE VLAN entry:REG_MCAST_FLOOD_INDEX -> ALE_VLAN_MASK_MUXy
The commit b361da837392 ("net: netcp: ale: add proper ale entry mask bits
for netcp switch ALE") update ALE code to support such ALE entries, it is
always used ALE_VLAN_MASK_MUX0_REG index in ALE VLAN entry for unreg mcast
packets mask configuration, which is read-only, at least for AM65xx MCU
CPSW2G NUSS and 66AK2E/L NUSS. As result unreg mcast packets are allowed
always.
Hence, update ALE code to use ALE_VLAN_MASK_MUX1_REG index for ALE VLAN
entries to configure unreg mcast port mask.

-> may schedule async probe
phydev = mdiobus_get_phy()
<phydev action involving PHY driver>
or
phydev = phy_device_create()
-> loads PHY driver module

-> may schedule async probe
<phydev action involving PHY driver>
then we expect the PHY driver to be bound to the phydev when triggering
the action. This may not be the case in case of asynchronous probing.
Therefore ensure that PHY drivers are probed synchronously.
Default still is sync probing, except async probing is explicitly
requested. I saw some comments that the intention is to promote
async probing for more parallelism in boot process and want to be

Each snapshot created for a devlink region must have an id. These ids
are supposed to be unique per "event" that caused the snapshot to be
created. Drivers call devlink_region_snapshot_id_get to obtain a new id
to use for a new event trigger. The id values are tracked per devlink,
so that the same id number can be used if a triggering event creates
multiple snapshots on different regions.
There is no mechanism for snapshot ids to ever be reused. Introduce an
xarray to store the count of how many snapshots are using a given id,
replacing the snapshot_id field previously used for picking the next id.
The devlink_region_snapshot_id_get() function will use xa_alloc to
insert an initial value of 1 value at an available slot between 0 and
U32_MAX.
The new __devlink_snapshot_id_increment() and
__devlink_snapshot_id_decrement() functions will be used to track how
many snapshots currently use an id.
Drivers must now call devlink_snapshot_id_put() in order to release
their reference of the snapshot id after adding region snapshots.
By tracking the total number of snapshots using a given id, it is
possible for the decrement() function to erase the id from the xarray
when it is not in use.
With this method, a snapshot id can become reused again once all
snapshots that referred to it have been deleted via
DEVLINK_CMD_REGION_DEL, and the driver has finished adding snapshots.
This work also paves the way to introduce a mechanism for userspace to
request a snapshot.

The devlink_snapshot_id_get() function returns a snapshot id. The
snapshot id is a u32, so there is no way to indicate an error code.
A future change is going to possibly add additional cases where this
function could fail. Refactor the function to return the snapshot id in
an argument, so that it can return zero or an error value.
This ensures that snapshot ids cannot be confused with error values, and
aids in the future refactor of snapshot id allocation management.
Because there is no current way to release previously used snapshot ids,
add a simple check ensuring that an error is reported in case the
snapshot_id would over flow.
