i225 devices only have copper phy media type. There is no point in
checking phy media type during the phy initialization. This patch cleans
up a pointless check.

The driver tried to use Linux' native software I2C bus master
(i2c-algo-bits) for exporting the I2C interface that talks to the SFP
cage(s) towards userspace. As-is, however, the physical SCL/SDA pins
were not moving at all, staying at logical 1 all the time.
The main culprit was the I2CPARAMS register where igb was not setting
the I2CBB_EN bit. That meant that all the careful signal bit-banging was
actually not being propagated to the chip pads (I verified this with a
scope).
The bit-banging was not correct either, because I2C is supposed to be an
open-collector bus, and the code was driving both lines via a totem
pole. The code was also trying to do operations which did not make any
sense with the i2c-algo-bits, namely manipulating both SDA and SCL from
igb_set_i2c_data (which is only supposed to set SDA). I'm not sure if
that was meant as an optimization, or was just flat out wrong, but given
that the i2c-algo-bits is set up to work with a totally dumb GPIO-ish
implementation underneath, there's no need for this code to be smart.
The open-drain vs. totem-pole is fixed by the usual trick where the
logical zero is implemented via regular output mode and outputting a
logical 0, and the logical high is implemented via the IO pad configured
as an input (thus floating), and letting the mandatory pull-up resistors
do the rest. Anything else is actually wrong on I2C where all devices
are supposed to have open-drain connection to the bus.
The missing I2CBB_EN is set (along with a safe initial value of the
GPIOs) just before registering this software I2C bus.
The chip datasheet mentions HW-implemented I2C transactions (SFP EEPROM
reads and writes) as well, but I'm not touching these for simplicity.
Tested on a LR-Link LRES2203PF-2SFP (which is an almost-miniPCIe form
factor card, a cable, and a module with two SFP cages). There was one
casualty, an old broken SFP we had laying around, which was used to
solder some thin wires as a DIY I2C breakout. Thanks for your service.
With this patch in place, I can `i2cdump -y 3 0x51 c` and read back data
which make sense. Yay.

Add firmware (FW) version 4.0 support for Marvell Prestera
driver.
Major changes have been made to new v4.0 FW ABI to add support
of new features, introduce the stability of the FW ABI and ensure
better forward compatibility for the future driver vesrions.
Current v4.0 FW feature set support does not expect any changes
to ABI, as it was defined and tested through long period of time.
The ABI may be extended in case of new features, but it will not
break the backward compatibility.
ABI major changes done in v4.0:
- L1 ABI, where MAC and PHY API configuration are split.
- ACL has been split to low-level TCAM and Counters ABI
to provide more HW ACL capabilities for future driver
versions.
To support backward support, the addition compatibility layer is
required in the driver which will have two different codebase under
"if FW-VER elif FW-VER else" conditions that will be removed
in the future anyway, So, the idea was to break backward support
and focus on more stable FW instead of supporting old version
with very minimal and limited set of features/capabilities.
Improve FW msg validation:
* Use __le64, __le32, __le16 types in msg to/from FW to
catch endian mismatch by sparse.
* Use BUILD_BUG_ON for structures sent/recv to/from FW.

mvneta does not support asymetric pause modes, and it flags this by the
lack of AsymPause in the supported field. When setting pause modes, we
check that pause->rx_pause == pause->tx_pause, but only when pause
autoneg is enabled. When pause autoneg is disabled, we still allow
pause->rx_pause != pause->tx_pause, which is incorrect when the MAC
does not support asymetric pause, and causes mvneta to issue a warning.
Fix this by removing the test for pause->autoneg, so we always check
that pause->rx_pause == pause->tx_pause for network devices that do not
support AsymPause.

For each rate change command submission, the FW has to do a phy

sending mailbox commands and re-enabled once the command submission

Clang is a little more pedantic than GCC, which does not warn when
falling through to a case that is just break or return. Clang's version
is more in line with the kernel's own stance in deprecated.rst, which
states that all switch/case blocks must end in either break,

Some devices have support for loading the PHY FW and in some cases this
can fail. When this fails, the FW will set the corresponding bit in the
link info structure. Also, the FW will send a link event if the correct
link event mask bit is set. Add support for printing an error message
when the PHY FW load fails during any link configuration flow and the
link event flow.
Since ice_check_module_power() is already doing something very similar
add a new function ice_check_link_cfg_err() so any failures reported in
the link info's link_cfg_err member can be printed in this one function.
Also, add the new ICE_FLAG_PHY_FW_LOAD_FAILED bit to the PF's flags so

Part of virtchannel messages are treated in different way in switchdev
mode to block configuring VFs from iavf driver side. This blocking was
done by doing nothing and returning success, event without sending
response.
Not sending response for opcodes that aren't supported in switchdev mode
leads to block iavf driver message handling. This happens for example
when vlan is configured at VF config time (VLAN module is already
loaded).
To get rid of it ice driver should answer for each VF message. In
switchdev mode:
- for adding/deleting VLAN driver should answer success without doing
anything to allow creating vlan device on VFs
- for enabling/disabling VLAN stripping and promiscuous mode driver
should answer not supported, this feature in switchdev can be only
set from host side

Mostly reuse code from Geneve and VXLAN in TC parsing code. Add new GRE
header to match on correct fields. Create new dummy packets with GRE

Instead of checking if any encap values are presented in TC flower,
check if device is tunnel type or redirect is to tunnel device. This
will allow adding all combination of rules. For example filters only
with inner fields.
Return error in case device isn't tunnel but encap values are presented.

- create tunnel device
ip l add $NVGRE_DEV type gretap remote $NVGRE_REM_IP local $VF1_IP \

Geneve example:
- create tunnel device
ip l add $GENEVE_DEV type geneve id $GENEVE_VNI dstport $GENEVE_PORT \
remote $GENEVE_IP
- add TC filter (in switchdev mode)

Implement indirect notification mechanism to support offloading TC rules
on tunnel devices.
Keep indirect block list in netdev priv. Notification will call setting
tc cls flower function. For now we can offload only ingress type. Return
not supported for other flow block binder.

This reverts commit 3bda2e5df476417b6d08967e2d84234a59d57b1c.
According to discussion with Andrew as follow:
https://lore.kernel.org/netdev/09eda9fe-196b-006b-6f01-f54e75715961@huawei.com/
HNS3 driver needs to separate pause autoneg from general autoneg, so revert
this incorrect patch.

Commit 406f42fa0d3c ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look
up. To maintain netdev->dev_addr in this tree we need to make all
the writes to it go through appropriate helpers.
Even though the current code uses dev->addr_len the we can switch
to eth_hw_addr_set() instead of dev_addr_set(). The netdev is
always allocated by alloc_etherdev_mq() and there are at least two
places which assume Ethernet address:
- the line below calling eth_hw_addr_random()
- virtnet_set_mac_address() -> eth_commit_mac_addr_change()

CN10k SoCs use atomic stores of up to 128 bytes to submit
packets/instructions into co-processor cores. The enqueueing is performed
using Large Memory Transaction Store (LMTST) operations. They allow for
lockless enqueue operations - i.e., two different CPU cores can submit
instructions to the same queue without needing to lock the queue or
synchronize their accesses.
This patch implements a new debugfs entry for dumping LMTST map
table present on CN10K, as this might be very useful to debug any issue
in case of shared LMTST region among multiple pci functions.
