There is an arbitrary difference between the prototypes of
bus_find_device() and class_find_device() preventing their callers
from passing the same pair of data and match() arguments to both of
them, which is the const qualifier used in the prototype of
class_find_device(). If that qualifier is also used in the
bus_find_device() prototype, it will be possible to pass the same
match() callback function to both bus_find_device() and
class_find_device(), which will allow some optimizations to be made in
order to avoid code duplication going forward. Also with that, constify
the "data" parameter as it is passed as a const to the match function.
For this reason, change the prototype of bus_find_device() to match
the prototype of class_find_device() and adjust its callers to use the
const qualifier in accordance with the new prototype of it.

For tx path, in most cases, we still have to take refcnt on the dst
cause the caller is caching the dst somewhere. But it still is
beneficial to make use of RT6_LOOKUP_F_DST_NOREF flag while doing the
route lookup. It is cause this flag prevents manipulating refcnt on
net->ipv6.ip6_null_entry when doing fib6_rule_lookup() to traverse each
routing table. The null_entry is a shared object and constant updates on
it cause false sharing.
We converted the current major lookup function ip6_route_output_flags()
to make use of RT6_LOOKUP_F_DST_NOREF.
Together with the change in the rx path, we see noticable performance
boost:
I ran synflood tests between 2 hosts under the same switch. Both hosts
have 20G mlx NIC, and 8 tx/rx queues.
Sender sends pure SYN flood with random src IPs and ports using trafgen.
Receiver has a simple TCP listener on the target port.
Both hosts have multiple custom rules:
- For incoming packets, only local table is traversed.
- For outgoing packets, 3 tables are traversed to find the route.
The packet processing rate on the receiver is as follows:
- Before the fix: 3.78Mpps
- After the fix: 5.50Mpps

This is a no-op that simply moves all locking and unlocking of
->reg_lock into trivial helpers. I did that to be able to easily add
some ad hoc instrumentation to those helpers to get some information
on contention and hold times of the mutex. Perhaps others want to do
something similar at some point, so this frees them from doing the
'sed -i' yoga, and have a much smaller 'git diff' while fiddling.

The current code of create_queues_with_size_backoff() allows the ring size
to become as small as ENA_MIN_RING_SIZE/2. This is a bug since we don't
want the queue ring to be smaller than ENA_MIN_RING_SIZE
In this commit we change the loop's termination condition to look at the
queue size of the next iteration instead of that of the current one,
so that the minimal queue size again becomes ENA_MIN_RING_SIZE.

When transmitting certain PTP frames, e.g. SYNC and DELAY_REQ, the
PTP daemon, e.g. ptp4l, is polling the driver for the frame transmit
hardware timestamp. The polling will most likely timeout if the tx
coalesce is enabled due to the Interrupt-on-Completion (IC) bit is
not set in tx descriptor for those frames.
This patch will ignore the tx coalesce parameter and set the IC bit
when transmitting PTP frames which need to report out the frame
transmit hardware timestamp to user space.

When ADDSUB bit is set, the system time seconds field is calculated as
the complement of the seconds part of the update value.
For example, if 3.000000001 seconds need to be subtracted from the
system time, this field is calculated as
2^32 - 3 = 4294967296 - 3 = 0x100000000 - 3 = 0xFFFFFFFD
Previously, the 0x100000000 is mistakenly written as 100000000.
This is further simplified from
sec = (0x100000000ULL - sec);
to
sec = -sec;

The MPPE code uses the sync skcipher to invoke the ecb(arc4) skcipher,
of which only a single generic C code implementation exists. This means
that going through all the trouble of using scatterlists etc buys us
very little, and we're better off just invoking the arc4 library directly.
Note that the SHA1 shash used by this driver has several accelerated
implementations for various architectures, so retaining that part does
make sense.

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.
Since it has no performance penalty let's remove that and simplify the Rx
path a bit

Since we changed the Tx ring handling and now depends on bit31 to figure
out the owner of the descriptor, we should initialize this every time
the device goes down-up instead of doing it once on driver init. If the
value is not correctly initialized the device won't have any available
descriptors

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.
