====================
ice: one by one port representors creation
Michal Swiatkowski says:
Currently ice supports creating port representors only for VFs. For that
use case they can be created and removed in one step.
This patchset is refactoring current flow to support port representor
creation also for subfunctions and SIOV. In this case port representors
need to be created and removed one by one. Also, they can be added and
removed while other port representors are running.
To achieve that we need to change the switchdev configuration flow.
Three first patches are only cosmetic (renaming, removing not used code).
Next few ones are preparation for new flow. The most important one
is "add VF representor one by one". It fully implements new flow.
New type of port representor (for subfunction) will be introduced in
follow up patchset.
* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
ice: reserve number of CP queues
ice: adjust switchdev rebuild path
ice: add VF representors one by one
ice: realloc VSI stats arrays
ice: set Tx topology every time new repr is added
ice: allow changing SWITCHDEV_CTRL VSI queues
ice: return pointer to representor
ice: make representor code generic
ice: remove VF pointer reference in eswitch code
ice: track port representors in xarray
ice: use repr instead of vf->repr
ice: track q_id in representor
ice: remove unused control VSI parameter
ice: remove redundant max_vsi_num variable
ice: rename switchdev to eswitch

Rebuilding CP VSI each time the PR is created drastically increase the
time of maximum VFs creation. Add function to reserve number of CP
queues to deal with this problem.
Use the same function to decrease number of queues in case of removing
VFs. Assume that caller of ice_eswitch_reserve_cp_queues() will also
call ice_eswitch_attach/detach() correct number of times.
Still one by one PR adding is handy for VF resetting routine.

There is no need to use specific functions for rebuilding path. Let's
use current implementation by removing all representors and as the
result remove switchdev environment.
It will be added in devices rebuild path. For example during adding VFs,
port representors for them also will be created.
Rebuild control plane VSI before removing representors with INIT_VSI
flag set to reinit VSI in hardware after reset.

Implement adding representors one by one. Always set switchdev
environment when first representor is being added and clear environment
when last one is being removed.
Basic switchdev configuration remains the same. Code related to creating
and configuring representor was changed.
Instead of setting whole representors in one function handle only one
representor in setup function. The same with removing representors.
Stop representors when new one is being added or removed. Stop means,
disabling napi, stopping traffic and removing slow path rule. It is
needed because ::q_id will change after remapping, so each representor
will need new rule.
When representor are stopped rebuild control plane VSI with one more or
one less queue. One more if new representor is being added, one less if
representor is being removed.
Bridge port is removed during unregister_netdev() call on PR, so there
is no need to call it from driver side.
After that do remap new queues to correct vector. At the end start all
representors (napi enable, start queues, add slow path rule).

It is needed to track correct Tx topology. Update it every time new
representor is created or remove node in case of removing corresponding
representor.

Representor code needs to be independent from specific device type, like
in this case VF. Make generic add / remove representor function and
specific add VF / rem VF function. New device types will follow this
scheme.

Make eswitch code generic by removing VF pointer reference in functions.
It is needed to support eswitch mode for other type of devices.
Previously queue id used for Rx was based on VF number. Use ::q_id saved
in port representor instead.
After adding or removing port representor ::q_id value can change. It
isn't good idea to iterate over representors list using this value.
Use xa_find starting from the first one instead to get next port
representor to remap.
The number of port representors has to be equal to ::num_rx/tx_q. Warn if
it isn't true.

Instead of assuming that each VF has pointer to port representor save it
in xarray. It will allow adding port representor for other device types.
Drop reference to VF where it is use only to get port representor. Get
it from xarray instead.
The functions will no longer by specific for VF, rename them.
Track id assigned by xarray in port representor structure. The id can't
be used as ::q_id, because it is fixed during port representor lifetime.
::q_id can change after adding / removing other port representors.
Side effect of removing VF pointer is that we are losing VF MAC
information used in unrolling. Store it in port representor as parent
MAC.

priority range 0-31, where firmware 4.10+ would support the range 0-9

* 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.

Get ahead of the game and fix all the -Wformat=2 noted warnings in the
intel drivers directory.
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.

Fix -Wformat-truncated warnings to complete the intel directories' W=1
clean efforts. The W=1 recently got enhanced with a few new flags and
this brought up some new warnings.
Switch to using kasprintf() when possible so we always allocate the
right length strings.

One thing is broken in the safe mode, that is
ice_deinit_features() is being executed even
that ice_init_features() was not causing stack

Add check on the top of the function.

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()

Since the introduction of the ice driver the code has been
double-shifting the RSS enabling field, because the define already has
shifts in it and can't have the regular pattern of "a << shiftval &
mask" applied.
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
regular -next process sometime after this one.

When one of the LAG interfaces is in switchdev mode, setting default rule
can't be done.
The interface on which switchdev is running has ice_set_rx_mode() blocked
to avoid default rule adding (and other rules). The other interfaces
(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.
