Add user template explicit support. At this moment, max
TCAM rule size is utilized for all rules, doesn't matter
which and how much flower matches are provided by user. It
means that some of TCAM space is wasted, which impacts
the number of filters that can be offloaded.
Introducing the template, allows to have more HW offloaded
filters by specifying the template explicitly.
Example:
tc qd add dev PORT clsact
tc chain add dev PORT ingress protocol ip \
flower dst_ip 0.0.0.0/16
tc filter add dev PORT ingress protocol ip \
flower skip_sw dst_ip 1.2.3.4/16 action drop
NOTE: chain 0 is the default chain id for "tc chain" & "tc filter"
command, so it is omitted in the example above.
This patch adds only template support for default chain 0 suppoerted
by prestera driver at this moment. Chains are not supported yet,
and will be added later.

Allow drivers to pass metadata along with packet data to the device.
Introduce a new metadata descriptor type
* GVE_TXD_MTD
This descriptor is optional. If present it immediate follows the
packet descriptor and precedes the segment descriptor.
This descriptor may be repeated. Multiple metadata descriptors may
follow. There are no immediate uses for this, this is for future
proofing. At present devices allow only 1 MTD descriptor.
The lower four bits of the type_flags field encode GVE_TXD_MTD.
The upper four bits of the type_flags field encodes a *sub*type.
Introduce one such metadata descriptor subtype
* GVE_MTD_SUBTYPE_PATH
This shares path information with the device for network failure
discovery and robust response:
Linux derives ipv6 flowlabel and ECMP multipath from sk->sk_txhash,
and updates this field on error with sk_rethink_txhash. Allow the host
stack to do the same. Pass the tx_hash value if set. Also communicate
whether the path hash is set, or more exactly, what its type is. Define
two common types
GVE_MTD_PATH_HASH_NONE
GVE_MTD_PATH_HASH_L4
Concrete examples of error conditions that are resolved are
mentioned in the commits that add sk_rethink_txhash calls. Such as
commit 7788174e8726 ("tcp: change IPv6 flow-label upon receiving
spurious retransmission").
Experimental results mirror what the theory suggests: where IPv6
FlowLabel is included in path selection (e.g., LAG/ECMP), flowlabel
rotation on TCP timeout avoids the vast majority of TCP disconnects
that would otherwise have occurred during link failures in long-haul
backbones, when an alternative path is available.
Rotation can be applied to various bad connection signals, such as
timeouts and spurious retransmissions. In aggregate, such flow level
signals can help locate network issues. Define initial common states:
GVE_MTD_PATH_STATE_DEFAULT
GVE_MTD_PATH_STATE_TIMEOUT
GVE_MTD_PATH_STATE_CONGESTION
GVE_MTD_PATH_STATE_RETRANSMIT

mac_select_pcs() allows us to have an explicit point to query which
PCS the MAC wishes to use for a particular PHY interface mode, thereby
allowing us to add support to validate the link settings with the PCS.
Phylink will also use this to select the PCS to be used during a major
configuration event without the MAC driver needing to call
phylink_set_pcs().
Note that if mac_select_pcs() is present, the supported_interfaces
bitmap must be filled in; this avoids mac_select_pcs() being called
with PHY_INTERFACE_MODE_NA when we want to get support for all
interface types. Phylink will return an error in phylink_create()

The ice hardware contains an embedded chip with firmware which can be
updated using devlink flash. The firmware which runs on this chip is
referred to as the Embedded Management Processor firmware (EMP
firmware).
Activating the new firmware image currently requires that the system be
rebooted. This is not ideal as rebooting the system can cause unwanted
downtime.
In practical terms, activating the firmware does not always require a
full system reboot. In many cases it is possible to activate the EMP
firmware immediately. There are a couple of different scenarios to
cover.
* The EMP firmware itself can be reloaded by issuing a special update
to the device called an Embedded Management Processor reset (EMP
reset). This reset causes the device to reset and reload the EMP
firmware.
* PCI configuration changes are only reloaded after a cold PCIe reset.
Unfortunately there is no generic way to trigger this for a PCIe
device without a system reboot.
When performing a flash update, firmware is capable of responding with
some information about the specific update requirements.
The driver updates the flash by programming a secondary inactive bank
with the contents of the new image, and then issuing a command to
request to switch the active bank starting from the next load.
The response to the final command for updating the inactive NVM flash
bank includes an indication of the minimum reset required to fully
update the device. This can be one of the following:
* A full power on is required
* A cold PCIe reset is required
* An EMP reset is required
The response to the command to switch flash banks includes an indication
of whether or not the firmware will allow an EMP reset request.
For most updates, an EMP reset is sufficient to load the new EMP
firmware without issues. In some cases, this reset is not sufficient
because the PCI configuration space has changed. When this could cause
incompatibility with the new EMP image, the firmware is capable of
rejecting the EMP reset request.
Add logic to ice_fw_update.c to handle the response data flash update
AdminQ commands.
For the reset level, issue a devlink status notification informing the
user of how to complete the update with a simple suggestion like
"Activate new firmware by rebooting the system".
Cache the status of whether or not firmware will restrict the EMP reset
for use in implementing devlink reload.
Implement support for devlink reload with the "fw_activate" flag. This
allows user space to request the firmware be activated immediately.
For the .reload_down handler, we will issue a request for the EMP reset
using the appropriate firmware AdminQ command. If we know that the
firmware will not allow an EMP reset, simply exit with a suitable
netlink extended ACK message indicating that the EMP reset is not
available.
For the .reload_up handler, simply wait until the driver has finished
resetting. Logic to handle processing of an EMP reset already exists in
the driver as part of its reset and rebuild flows.
Implement support for the devlink reload interface with the
"fw_activate" action. This allows userspace to request activation of
firmware without a reboot.
Note that support for indicating the required reset and EMP reset
restriction is not supported on old versions of firmware. The driver can
determine if the two features are supported by checking the device
capabilities report. I confirmed support has existed since at least
version 5.5.2 as reported by the 'fw.mgmt' version. Support to issue the
EMP reset request has existed in all version of the EMP firmware for the
ice hardware.
Check the device capabilities report to determine whether or not the
indications are reported by the running firmware. If the reset
requirement indication is not supported, always assume a full power on
is necessary. If the reset restriction capability is not supported,
always assume the EMP reset is available.
Users can verify if the EMP reset has activated the firmware by using
the devlink info report to check that the 'running' firmware version has
updated. For example a user might do the following:
# Check current version
$ devlink dev info
# Update the device
$ devlink dev flash pci/0000:af:00.0 file firmware.bin
# Confirm stored version updated
$ devlink dev info
# Reload to activate new firmware
$ devlink dev reload pci/0000:af:00.0 action fw_activate
# Confirm running version updated
$ devlink dev info
Finally, this change does *not* implement basic driver-only reload
support. I did look into trying to do this. However, it requires
significant refactor of how the ice driver probes and loads everything.
The ice driver probe and allocation flows were not designed with such
a reload in mind. Refactoring the flow to support this is beyond the
scope of this change.

During probe and device reset, the ice driver reads some data from the
NVM image as part of ice_init_nvm. Part of this data includes a section
of the Option ROM which contains version information.
The function ice_get_orom_civd_data is used to locate the '$CIV' data
section of the Option ROM.
Timing of ice_probe and ice_rebuild indicate that the
ice_get_orom_civd_data function takes about 10 seconds to finish
executing.
The function locates the section by scanning the Option ROM every 512
bytes. This requires a significant number of NVM read accesses, since
the Option ROM bank is 500KB. In the worst case it would take about 1000
reads. Worse, all PFs serialize this operation during reload because of
acquiring the NVM semaphore.
The CIVD section is located at the end of the Option ROM image data.
Unfortunately, the driver has no easy method to determine the offset
manually. Practical experiments have shown that the data could be at
a variety of locations, so simply reversing the scanning order is not
sufficient to reduce the overall read time.
Instead, copy the entire contents of the Option ROM into memory. This
allows reading the data using 4Kb pages instead of 512 bytes at a time.
This reduces the total number of firmware commands by a factor of 8. In
addition, reading the whole section together at once allows better
indication to firmware of when we're "done".
Re-write ice_get_orom_civd_data to allocate virtual memory to store the
Option ROM data. Copy the entire OptionROM contents at once using
ice_read_flash_module. Finally, use this memory copy to scan for the
'$CIV' section.
This change significantly reduces the time to read the Option ROM CIVD
section from ~10 seconds down to ~1 second. This has a significant
impact on the total time to complete a driver rebuild or probe.

The ice_devlink_flash_update function performs a few upfront checks and
then calls ice_flash_pldm_image.
Most if these checks make more sense in the context of code within
ice_flash_pldm_image. Merge ice_devlink_flash_update and
ice_flash_pldm_image into one function, placing it in ice_fw_update.c
Since this is still the entry point for devlink, call the function
ice_devlink_flash_update instead of ice_flash_pldm_image. This leaves a
single function which handles the devlink parameters and then initiates
a PLDM update.
With this change, the ice_devlink_flash_update function in
ice_fw_update.c becomes the main entry point for flash update. It
elimintes some unnecessary boiler plate code between the two previous
functions. The ultimate motivation for this is that it eases supporting
a dry run with the PLDM library in a future change.

The ice_devlink_flash_update function performs a few checks and then
calls ice_flash_pldm_image. One of these checks is to call
ice_check_for_pending_update. This function checks if the device has
a pending update, and cancels it if so. This is necessary to allow
a new flash update to proceed.
We want to refactor the ice code to eliminate ice_devlink_flash_update,
moving its checks into ice_flash_pldm_image.
To do this, ice_check_for_pending_update will become static, and only
called by ice_flash_pldm_image. To make this change easier to review,
first just move the function up within the ice_fw_update.c file.
While at it, note that the function has a misleading name. Its primary
action is to cancel a pending update. Using the verb "check" does not
imply this. Rename it to ice_cancel_pending_update.

We have a region for reading the contents of the NVM flash as
a snapshot. This region does not allow reading the Shadow RAM, as it
always passes the FLASH_ONLY bit to the low level firmware interface.
Add a separate shadow-ram region which will allow snapshot of the
current contents of the Shadow RAM. This data is built from the NVM
contents but is distinct as the device builds up the Shadow RAM during
initialization, so being able to snapshot its contents can be useful
when attempting to debug flash related issues.
Fix the comment description of the nvm-flash region which incorrectly
stated that it filled the shadow-ram region, and add a comment
explaining that the nvm-flash region does not actually read the Shadow
RAM.

a reference on a resource. Namely, the KVDL entry where the IPv6
underlay destination IP is stored. When such an FDB entry is deleted, it

The device supports forwarding entries such as routes and FDBs that
perform tunnel (e.g., VXLAN, IP-in-IP) encapsulation or decapsulation.
When the underlay is IPv6, these entries do not encode the 128 bit IPv6
address used for encapsulation / decapsulation. Instead, these entries
encode a 24 bit pointer to an array called KVDL where the IPv6 address
is stored.
Currently, only IP-in-IP with IPv6 underlay is supported, but subsequent
patches will add support for VxLAN with IPv6 underlay. To avoid
duplicating the logic required to store and retrieve these IPv6
addresses, introduce a hash table that will store the mapping between
IPv6 addresses and their KVDL index.

It seems I missed that most ethnl_parse_header_dev_get() callers
declare an on-stack struct ethnl_req_info, and that they simply call
dev_put(req_info.dev) when about to return.
Add ethnl_parse_header_dev_put() helper to properly untrack
reference taken by ethnl_parse_header_dev_get().

Move goto action checks from parse nic/fdb funcs into the tc action
infra goto post parse op.
While moving this part also use NL_SET_ERR_MSG_MOD() instead of
NL_SET_ERR_MSG().

The post_parse() op should be called after the parse op was called
for all actions. It could be an action state is dependent on other
actions. In the new op an action can fail the parse if the state
is not valid anymore.

There is no reason to wait with the kmalloc to after parsing all
other actions. There could still be a failure later and before
offloading the rule. So alloc the mem when parsing.
The memory is being released on mlx5e_flow_put() which is called
also on error flow.
