Add a fixme comment for the last remaining incorrect usage of
state->speed in the mac_config() method, which is strangely in a code
path which is only run when the PHY interface mode changes.
This means if we are in RGMII mode, changes in state->speed will not
cause the INTF_MODE, TRGMII_RCK_CTRL and TRGMII_TCK_CTRL registers to
be set according to the speed, nor will the TRGPLL clock be set to the
correct value.

Phylink does not guarantee that state->duplex will be set correctly in

Phylink does not guarantee that state->speed will be set correctly in
the mac_config() call, so it's a bug that the driver makes use of it.
Moreover, it is making use of it in a function that is only ever called
for 1000BASE-X and 2500BASE-X which operate at a fixed speed which
happens to be the same setting irrespective of the interface mode. We
can simply remove the switch statement and just set the SGMII interface
speed.

PTP one step sync packets cannot have CSUM padding and insertion in
SW since time stamp is inserted on the fly by HW.
In addition, ptp4l version 3.0 and above report an error when skb
timestamps are reported for packets that not processed for TX TS
after transmission.
Add a helper to identify PTP one step sync and fix the above two

====================
pull-request: can-next 2022-05-19
Oliver Hartkopp contributes a patch for the ISO-TP CAN protocol to
update the validation of address information during bind.
The next patch is by Jakub Kicinski and converts the CAN network
drivers from netif_napi_add() to the netif_napi_add_weight() function.
Another patch by Oliver Hartkopp removes obsolete CAN specific LED
support.
Vincent Mailhol's patch for the mcp251xfd driver fixes a
-Wunaligned-access warning by clang-14.

clang emits a -Wunaligned-access warning on union
mcp251xfd_tx_ojb_load_buf.
The reason is that field hw_tx_obj (not declared as packed) is being
packed right after a 16 bits field inside a packed struct:
| union mcp251xfd_tx_obj_load_buf {
| struct __packed {
| struct mcp251xfd_buf_cmd cmd;
| /* ^ 16 bits fields */
| struct mcp251xfd_hw_tx_obj_raw hw_tx_obj;
| /* ^ not declared as packed */
| } nocrc;
| struct __packed {
| struct mcp251xfd_buf_cmd_crc cmd;
| struct mcp251xfd_hw_tx_obj_raw hw_tx_obj;
| __be16 crc;
| } crc;
| } ____cacheline_aligned;
Starting from LLVM 14, having an unpacked struct nested in a packed
struct triggers a warning. c.f. [1].
This is a false positive because the field is always being accessed
with the relevant put_unaligned_*() function. Adding __packed to the
structure declaration silences the warning.

common LED support with CONFIG_LEDS_TRIGGER_NETDEV should do this work
now the code can be removed as preparation for a CAN netdevice Kconfig

The ADIN1300 supports generating certain clocks on its GP_CLK pin, as
well as providing the reference clock on CLK25_REF.
Add support for selecting the clock via device-tree properties.
Technically the phy also supports a recovered 125MHz clock for
synchronous ethernet. SyncE should be configured dynamically at
runtime, however Linux does not currently have a toggle for this,
so support is explicitly omitted.

Netfilter fixes for net
1) Reduce number of hardware offload retries from flowtable datapath
which might hog system with retries, from Felix Fietkau.
2) Skip neighbour lookup for PPPoE device, fill_forward_path() already
provides this and set on destination address from fill_forward_path for
PPPoE device, also from Felix.
4) When combining PPPoE on top of a VLAN device, set info->outdev to the
PPPoE device so software offload works, from Felix.
5) Fix TCP teardown flowtable state, races with conntrack gc might result
in resetting the state to ESTABLISHED and the time to one day. Joint
work with Oz Shlomo and Sven Auhagen.
6) Call dst_check() from flowtable datapath to check if dst is stale
instead of doing it from garbage collector path.
7) Disable register tracking infrastructure, either user-space or
kernel need to pre-fetch keys inconditionally, otherwise register
tracking assumes data is already available in register that might
not well be there, leading to incorrect reductions.

The AST2600 when using the i210 NIC over NC-SI has been observed to
produce incorrect checksum results with specific MTU values. This was
first observed when sending data across a long distance set of networks.
On a local network, the following test was performed using a 1MB file of
random data.
On the receiver run this script:
#!/bin/bash
while [ 1 ]; do
# Zero the stats
nstat -r > /dev/null
nc -l 9899 > test-file
# Check for checksum errors
TcpInCsumErrors=$(nstat | grep TcpInCsumErrors)
if [ -z "$TcpInCsumErrors" ]; then
echo No TcpInCsumErrors
else
echo TcpInCsumErrors = $TcpInCsumErrors
fi
done
On an AST2600 system:
# nc <IP of receiver host> 9899 < test-file
The test was repeated with various MTU values:
# ip link set mtu 1410 dev eth0
The observed results:
1500 - good
1434 - bad
1400 - good
1410 - bad
1420 - good
The test was repeated after disabling tx checksumming:
# ethtool -K eth0 tx-checksumming off
And all MTU values tested resulted in transfers without error.
An issue with the driver cannot be ruled out, however there has been no
bug discovered so far.
David has done the work to take the original bug report of slow data
transfer between long distance connections and triaged it down to this
test case.
The vendor suspects this this is a hardware issue when using NC-SI. The
fixes line refers to the patch that introduced AST2600 support.

phy_data, this led to the phy status check either succeeding immediately
or looping continuously for 2 seconds before emitting a noisy err-level
timeout. This message went out to the console even though there was no
actual problem.
Instead, first check if there is read_reg function pointer. If not,

This series contains updates to ice driver only.
Arkadiusz prevents writing of timestamps when rings are being
configured to resolve null pointer dereference.
Paul changes a delayed call to baseline statistics to occur immediately
which was causing misreporting of statistics due to the delay.
Michal fixes incorrect restoration of interrupt moderation settings.

The name, regs_size and overrides members in struct ksz_device are
unused. Hence remove it.
And host_mask is used in only place of ksz8795.c file, which can be
replaced by dev->info->cpu_ports

This patch add the support for phylink_get_caps for ksz8795 and ksz9477
series switch. It updates the struct ksz_switch_chip with the details of
the internal phys and xmii interface. Then during the get_caps based on
the bits set in the structure, corresponding phy mode is set.

mib->cnt_ptr resetting is handled in multiple places as part of
port_init_cnt(). Hence moved mib->cnt_ptr code to ksz common layer
and removed from individual product files.

ksz8795 and ksz9477 init function initializes the memory to dev->ports,
mib counters and assigns the ds real number of ports. Since both the
routines are same, moved the allocation of port memory to
ksz_switch_register after init.

The ksz88xx family has one set of mib_names. The ksz87xx, ksz9477,
LAN937x based switches has one set of mib_names. In order to remove
redundant declaration, moved the struct mib_names to ksz_chip_data
structure.

This patch perform the compatibility check for the device after the chip
detect is done. It is to prevent the mismatch between the device
compatible specified in the device tree and actual device found during
the detect. The ksz9477 device doesn't use any .data in the
of_device_id. But the ksz8795_spi uses .data for assigning the regmap
between 8830 family and 87xx family switch. Changed the regmap
assignment based on the chip_id from the .data.

This patch moves the ksz_chip_data in ksz8795 and ksz9477 to ksz_common.
At present, the dev->chip_id is iterated with the ksz_chip_data and then
copy its value to the ksz_dev structure. These values are declared as
constant.
Instead of copying the values and referencing it, this patch update the
dev->info to the ksz_chip_data based on the chip_id in the init
function. And also update the ksz_chip_data values for the LAN937x based
switches.

The port_cnt value in the structure is not used in the switch_init.
Instead it uses the fls(chip->cpu_port), this is due to one of port in
the ksz8794 unavailable. The cpu_port for the 8794 is 0x10, fls(0x10) =
5, hence updating it directly in the ksz_chip_data structure in order to
same with all the other switches in ksz8795.c and ksz9477.c files.

Make the firmware's life easier and always accept MCAST frames. If
needed, drop them in the driver. We need to filter out MCAST frames
in order not to have false positives in the decryption check. If we
accept MCAST frames before we have the GKT installed, we'll end up
complaining that we can't decrypt the frame.
Implement the same filtering, but in the driver.
