If an attribute of an aggregate interface disqualifies it from supporting
SRIOV, the driver will unwind the SRIOV support. Currently the driver is
clearing the feature bit for all interfaces in the aggregate, but this is

* Replace the references to ancient and long removed ICE_SUCCESS and

* Return -ENOENT instead of -ENOTBLK, as a more common way to indicate that
an entry doesn't exist.
* Avoid the use of memset() and use simple static initialization for the

* Use FIELD_PREP to assign the node_type_ctx.
* Remove an unnecessary local variable to keep track of rec_node_handle,
just pass the node_handle pointer directly into ice_aq_get_netlist_node.

There are one set of i40e and iavf warnings I couldn't figure out how to
fix because the driver is already using vsnprintf without an explicit
"const char *" format string.
Tested with both gcc-12 and clang-15. I found gcc-12 runs clean after
this series but clang-15 is a little worried about the vsnprintf lines.

When the system boots into the crash dump kernel after a panic, the ice
networking device may still have pending transactions that can cause errors
or machine checks when the device is re-enabled. This can prevent the crash
dump kernel from loading the driver or collecting the crash data.
To avoid this issue, perform a function level reset (FLR) on the ice device
via PCIe config space before enabling it on the crash kernel. This will
clear any outstanding transactions and stop all queues and interrupts.
Restore the config space after the FLR, otherwise it was found in testing
that the driver wouldn't load successfully.
The following sequence causes the original issue:
- Load the ice driver with modprobe ice
- Enable SR-IOV with 2 VFs: echo 2 > /sys/class/net/eth0/device/sriov_num_vfs
- Trigger a crash with echo c > /proc/sysrq-trigger
- Load the ice driver again (or let it load automatically) with modprobe ice
- The system crashes again during pcim_enable_device()

double-shifting the RSS enabling field, because the define already has
shifts in it and can't have the regular pattern of "a << shiftval &

Most places in the code got it right, but one line was still wrong. Fix
this one location for easy backports to stable. An in-progress patch
fixes the defines to "standard" and will be applied as part of the

(without switchdev running but connected via bond with interface that
runs switchdev) can't follow the same scheme, because rx filtering needs
to be disabled when failover happens. Notification for bridge to set
promisc mode seems like good place to do that.

The recent support for DPLL introduced by commit 8a3a565ff2 ("ice: add
admin commands to access cgu configuration") and commit d7999f5ea6 ("ice:
implement dpll interface to control cgu") broke linking the ice driver if
CONFIG_PTP_1588_CLOCK=n:

The first commit broke things by calling functions in
ice_init_feature_support that are compiled as part of ice_ptp_hw.o,
including:
* ice_is_phy_rclk_present
* ice_is_clock_mux_present_e810t
* ice_is_cgU_present
The second commit continued the break by calling several CGU functions
defined in ice_ptp_hw.c in the DPLL code.
Because the ice_dpll.c file is compiled unconditionally, it will not
link when CONFIG_PTP_1588_CLOCK=n.
It might be possible to break this dependency and expose those functions
without CONFIG_PTP_1588_CLOCK, but that is not clear to me.
For the DPLL case, simply compile ice_dpll.o only when we have
CONFIG_PTP_1588_CLOCK. Add stub no-op implementation of ice_dpll_init() and
ice_dpll_uninit() when CONFIG_PTP_1588_CLOCK=n into ice_dpll.h
The other functions are part of checking the netlist to see if hardware
features are enabled. These checks don't really belong in ice_ptp_hw.c, and
make more sense as part of the ice_common.c file. We already have
ice_is_gps_in_netlist() in ice_common.c which is doing a similar check.
Move the functions into ice_common.c and rename them to have the similar
postfix of "in_netlist()" to be more expressive of what they are actually
checking.
This also makes the ice_find_netlist_node only called from within
ice_common.c, so its safe to mark it static and stop declaring it in the
ice_common.h header as well.

When the PF and VF drivers both support flexible rx descriptors and have
negotiated the VIRTCHNL_VF_OFFLOAD_RX_FLEX_DESC capability, the VF driver
queries the PF for the list of supported descriptor formats
(VIRTCHNL_OP_GET_SUPPORTED_RXDIDS). The PF driver is supposed to set the
supported_rxdids bits that correspond to the descriptor formats the
firmware implements. The legacy 32-byte rx desc format is always
supported, even though it is not expressed in GLFLXP_RXDID_FLAGS.
The ice driver does not advertise the legacy 32-byte rx desc support,
which leads to this failure to bring up the VF using the Intel
out-of-tree iavf driver:
iavf 0000:41:01.0: PF does not list support for default Rx descriptor format
...
iavf 0000:41:01.0: PF returned error -5 (VIRTCHNL_STATUS_ERR_PARAM) to our request 6
The in-tree iavf driver does not expose this bug, because it does not
yet implement VIRTCHNL_VF_OFFLOAD_RX_FLEX_DESC.
The ice driver must always set the ICE_RXDID_LEGACY_1 bit in
supported_rxdids. The Intel out-of-tree ice driver and the ice driver in
DPDK both do this.
I copied this piece of the code and the comment text from the Intel
out-of-tree driver.

There is a problem in HW in E822-based devices leading to race
condition.
It might happen that, in order:
- PF0 (which owns the PHC) requests few timestamps,
- PF1 requests a timestamp,
- interrupt is being triggered and both PF0 and PF1 threads are woken
up,
- PF0 got one timestamp, still waiting for others so not going to sleep,
- PF1 gets it's timestamp, process it and go to sleep,
- PF1 requests a timestamp again,
- just before PF0 goes to sleep timestamp of PF1 appear,
- PF0 finishes all it's timestamps and go to sleep (PF1 also sleeping).
That leaves PF1 timestamp memory not read, which lead to blocking the
next interrupt from arriving.
Fix it by adding auxiliary devices and only one driver to handle all the
timestamps for all PF's by PHC owner. In the past each PF requested it's
own timestamps and process it from the start till the end which causes
problem described above. Currently each PF requests the timestamps as
before, but the actual reading of the completed timestamps is being done
by the PTP auxiliary driver, which is registered by the PF which owns PHC.
Additionally, the newly introduced auxiliary driver/devices for PTP clock
owner will be used for other features in all products (including E810).

Since commit 43c4958a3d ("ice: Merge pin initialization of E810 and E810T
adapters"), the ice_ptp_setup_pins_e810() function has been used for both
E810 and E810-T devices. The new implementation only distinguishes between
whether the device has SMA control or not. It was assumed this is always
true for E810-T devices. In addition, it does not set the n_per_out value
appropriately when SMA control is enabled.
In some cases, the E810-T device may not have access to SMA control. In
that case, the E810-T device actually has access to fewer pins than a
standard E810 device.
Fix the implementation to correctly assign the appropriate pin counts for
E810-T devices both with and without SMA control. The mentioned commit
already includes the appropriate macro values for these pin counts but they
were unused.
Instead of assigning the default E810 values and then overwriting them,
handle the cases separately in order of E810-T with SMA, E810-T without
SMA, and then standard E810. This flow makes following the logic easier.

The ICE_F_PTP_EXTTS feature flag is ostensibly intended to support checking
whether the device supports external timestamp pins. It is only checked in
E810-specific code flows, and is enabled for all E810-based devices. E822
and E823 flows unconditionally enable external timestamp support.
This makes the feature flag meaningless, as it is always enabled. Just
unconditionally enable support for external timestamp pins and remove this
unnecessary flag.

The ice_fill_phy_msg_e822 function uses several macros to specify the
correct address when sending a sideband message to the PHY block in
hardware.
The names of these macros are fairly generic and confusing. Future
development is going to extend the driver to support new hardware families
which have different relationships between PHY and QUAD. Rename the macros
for clarity and to indicate that they are E822 specific. This also matches
closer to the hardware specification in the data sheet.

To ensure that the status bit for the timestamp index is cleared, ensure
that ice_clear_phy_tstamp implementations first read the timestamp out.

The ice driver has PTP support which works across a couple of different
device families. The device families each have different PHY hardware which
have unique requirements for programming.
Today, there is E810-based hardware, and E822-based hardware. To handle
this, the driver checks the ice_is_e810() function to separate between the
two existing families of hardware.
Future development is going to add new hardware designs which have further
unique requirements. To make this easier, introduce a phy_model field to
the HW structure. This field represents what PHY model the current device
has, and is used to allow distinguishing which logic a particular device
needs.
This will make supporting future upcoming hardware easier, by providing an
obvious place to initialize the PHY model, and by already using switch/case
statements instead of the previous if statements.
Astute reviewers may notice that there are a handful of remaining checks
for ice_is_e810() left in ice_ptp.c These conflict with some other
cleanup patches in development, and will be fixed in the near future.
