Commit ce4ab73ab0c27c ("net: stmmac: drop the reset delays from struct
stmmac_mdio_bus_data") moved the reset delay array from struct
stmmac_mdio_bus_data to a stack variable.
The values from the array inside struct stmmac_mdio_bus_data were
previously initialized to 0 because the struct was allocated using
devm_kzalloc(). The array on the stack has to be initialized
explicitly, else we might be reading garbage values.
Initialize all reset delays to 0 to ensure that the values are 0 if the
"snps,reset-delays-us" property is not defined.
This fixes booting at least two boards (MIPS pistachio marduk and ARM
sun8i H2+ Orange Pi Zero). These are hanging during boot when
initializing the stmmac Ethernet controller (as found by Kernel CI).
Both have in common that they don't define the "snps,reset-delays-us"
property.

This patch is needed before we can allow drivers to use page_pool for
DMA-mappings. Today with page_pool and XDP return API, it is possible to
remove the page_pool object (from rhashtable), while there are still
in-flight packet-pages. This is safely handled via RCU and failed lookups in
__xdp_return() fallback to call put_page(), when page_pool object is gone.
In-case page is still DMA mapped, this will result in page note getting
correctly DMA unmapped.
To solve this, the page_pool is extended with tracking in-flight pages. And
XDP disconnect system queries page_pool and waits, via workqueue, for all
in-flight pages to be returned.
To avoid killing performance when tracking in-flight pages, the implement
use two (unsigned) counters, that in placed on different cache-lines, and
can be used to deduct in-flight packets. This is done by mapping the
unsigned "sequence" counters onto signed Two's complement arithmetic
operations. This is e.g. used by kernel's time_after macros, described in
kernel commit 1ba3aab3033b and 5a581b367b5, and also explained in RFC1982.
The trick is these two incrementing counters only need to be read and
compared, when checking if it's safe to free the page_pool structure. Which
will only happen when driver have disconnected RX/alloc side. Thus, on a
non-fast-path.
It is chosen that page_pool tracking is also enabled for the non-DMA
use-case, as this can be used for statistics later.
After this patch, using page_pool requires more strict resource "release",
e.g. via page_pool_release_page() that was introduced in this patchset, and
previous patches implement/fix this more strict requirement.
Drivers no-longer call page_pool_destroy(). Drivers already call
xdp_rxq_info_unreg() which call xdp_rxq_info_unreg_mem_model(), which will
attempt to disconnect the mem id, and if attempt fails schedule the
disconnect for later via delayed workqueue.

The mlx5 driver is using page_pool, but not for DMA-mapping (currently), and
is a little too relaxed about returning or releasing page resources, as it
is not strictly necessary, when not using DMA-mappings.
As this patchset is working towards tracking page_pool resources, to know
about in-flight frames on shutdown. Then fix places where mlx5 leak
page_pool resource.
In case of dma_mapping_error, then recycle into page_pool.
In mlx5e_free_rq() moved the page_pool_destroy() call to after the
mlx5e_page_release() calls, as it is more correct.
In mlx5e_page_release() when no recycle was requested, then release page
from the page_pool, via page_pool_release_page().

In case driver fails to register the page_pool with XDP return API (via
xdp_rxq_info_reg_mem_model()), then the driver can free the page_pool
resources more directly than calling page_pool_destroy(), which does a
unnecessarily RCU free procedure.
This patch is preparing for removing page_pool_destroy(), from driver
invocation.

netsec_process_rx was running in a loop trying to process as many packets
as possible before re-enabling interrupts. With the recent DMA changes
this is not needed anymore as we manage to consume all the budget without
looping over the function.

This commit allows using the vlan Id and priority as parts of the key
for classification offload. These fields are extracted from the
outermost tag, if multiple tags are present.
Vlan Id and priority are considered as 2 different fields by the
classifier, however the fields are both appended in the Header Extracted
Key in the same layout as they are found in the tags. This means that
when steering only based on the prio, a 16-bit slot is still taken in
the HEK.
The classifier doesn't allow extracting the DEI bit from the tag, so we
explicitly prevent user from using this bit in the key.
This commit adds the vlan priotity as a compatible HEK field for
tagged traffic, meaning that we limit the possibility of extracting this
field only to the flows that contain tagged traffic.

The C2 TCAM used for classification uses a key (Header Extracted Key)
built by concatenating several fields extracted from the packet header.
After a lot of trial-and-error and some guess work, it seems the HEK is
right justified, with the first fields being stored in the MSB, then
concatenated up until the LSB.
Until now, this doesn't cause any issue since all HEK fields we use are
full bytes. However this is an issue for the upcoming VLAN id and pri
extraction, which aren't full bytes.
Rework the way we built that TCAM key, by changing the order in which we
append the fields.

The way we currently handle classification offload and RSS is by having
dedicated lookup sequences in the flow table, each being selected
depending on several fields being present in the packet header.
We need to make sure the classification operation we want to perform can
be done in each flow we want to insert it into. As an example,
classifying on VLAN tag can only be done on flows used for tagged
traffic.
This commit makes sure we don't insert rules in flows we aren't
compatible with.

When performing a TCAM lookup in the C2 engine, it's possible that
multiple entries match the packet. To make sure the correct entry match
when performing a lookup, the Flow Table can set a lookup type, which
will be used in the TCAM lookup, thus preventing such false-positives.
We need to make sure the RSS match doesn't interfere with other
classification lookups, hence we use a dedicated lookup_type for it.

A previous attempt to shut up the uninitialized variable use
warning was apparently insufficient. When CONFIG_PROFILE_ANNOTATED_BRANCHES
is set, gcc-8 still warns, because the unlikely() check in DP_NOTICE()
causes it to no longer track the state of all variables correctly:

addr = NIG_REG_PPF_TO_ENGINE_SEL + abs_ppfid * 0x4;

This is not a nice workaround, but always initializing the output from
qed_llh_abs_ppfid() at least shuts up the false positive reliably.

In some circumstances, the hardware can hand us a null receive
descriptor, with no data attached but otherwise valid. Unfortunately,
the driver was ill-equipped to handle such an event, and would stop
processing packets at that point.
To fix this, use the Descriptor Done bit instead of the size to
determine whether or not a descriptor is ready to be processed. Add some
checks to allow for unused buffers.

Add call to iavf_add_cloud_filter and iavf_del_cloud_filter from
iavf_process_aq_command to clear aq_required
IAVF_FLAG_AQ_ADD_CLOUD_FILTER and IAVF_FLAG_AQ_DEL_CLOUD_FILTER bits.
aq_required IAVF_FLAG_AQ_DEL_CLOUD_FILTER bit is being set in
iavf_down and iavf_delete_clsflower, and are never cleared.
aq_required IAVF_FLAG_AQ_ADD_CLOUD_FILTER bit is being set in
iavf_handle_reset and iavf_configure_clsflower, and are never
cleared.
Since the aq_required is not zero, iavf_watchdog_task is setting the
queue_delayed_work to 20 msec instead of the longer delay.

Refactor the watchdog state machine implementation.
Add the additional state __IAVF_COMM_FAILED to process
the PF communication fails. Prepare the watchdog state machine
to integrate with init state machine.

Remove the watchdog timer, instead declare watchdog task
as delayed work and use dedicated workqueue to service driver
tasks. The dedicated driver workqueue iavf_wq is common
for all driver instances.

Move the commands processing outside the watchdog_task()
function. This reduce length and complexity of the function
which is mainly designed to process the watchdog state machine.

There was a calculation error in virtchnl regarding the valid
length which was fixed recently and a corresponding change needs
to go into the code while we enable ADq.

iavf_add_vlan() is being called in atomic context
