Current implementation is such that the number of Send queues (SQs)
are decided on the device probe which is equal to the number of online
cpus. These SQs are allocated and deallocated in interface open and c
lose calls respectively.
This patch defines new APIs for initializing and deinitializing Send
queues dynamically and allocates more number of transmit queues for
QOS feature.

current implementation is such that tot_tx_queues contains both
xdp queues and normal tx queues. which will be allocated in interface
open calls and deallocated on interface down calls respectively.
With addition of QOS, where send quees are allocated/deallacated upon
user request Qos send queues won't be part of tot_tx_queues. So this
patch renames tot_tx_queues to non_qos_queues.

The current implementation of HTB offload returns the EINVAL error
for unsupported parameters like prio and quantum. This patch removes
the error returning checks for 'prio' parameter and populates its
value to tc_htb_qopt_offload structure such that driver can use the
same.
Add prio parameter check in mlx5 driver, as mlx5 devices are not capable
of supporting the prio parameter when htb offload is used. Report error
if prio parameter is set to a non-default value.

net: introduce skb_frag_fill_page_desc()
Most users use __skb_frag_set_page()/skb_frag_off_set()/
skb_frag_size_set() to fill the page desc for a skb frag.
It does not make much sense to calling __skb_frag_set_page()
without calling skb_frag_off_set(), as the offset may depend
on whether the page is head page or tail page, so add
skb_frag_fill_page_desc() to fill the page desc for a skb
frag.
In the future, we can make sure the page in the frag is
head page of compound page or a base page, if not, we
may warn about that and convert the tail page to head
page and update the offset accordingly, if we see a warning
about that, we also fix the caller to fill the head page
in the frag. when the fixing is done, we may remove the
warning and converting.
In this way, we can remove the compound_head() or use
page_ref_*() like the below case:
https://elixir.bootlin.com/linux/latest/source/net/core/page_pool.c#L881
https://elixir.bootlin.com/linux/latest/source/include/linux/skbuff.h#L3383

If a packet needs to be encapsulated towards a local destination IP, the
packet will undergo a "local bypass" and be injected into the Rx path as
if it was received by the target VXLAN device without undergoing
encapsulation. If such a device does not exist, the packet will be
dropped.
There are scenarios where we do not want to perform such a bypass, but
instead want the packet to be encapsulated and locally received by a
user space program for post-processing.
To that end, add a new VXLAN device attribute that controls whether a
"local bypass" is performed or not. Default to performing a bypass to
maintain existing behavior.

====================
Support for Wake-on-LAN for Broadcom PHYs
This patch series adds support for Wake-on-LAN to the Broadcom PHY
driver. Specifically the BCM54210E/B50212E are capable of supporting
Wake-on-LAN using an external pin typically wired up to a system's GPIO.
These PHY operate a programmable Ethernet MAC destination address
comparator which will fire up an interrupt whenever a match is received.
Because of that, it was necessary to introduce patch #1 which allows the
PHY driver's ->suspend() routine to be called unconditionally. This is
necessary in our case because we need a hook point into the device
suspend/resume flow to enable the wake-up interrupt as late as possible.
Patch #2 adds support for the Broadcom PHY library and driver for
Wake-on-LAN proper with the WAKE_UCAST, WAKE_MCAST, WAKE_BCAST,
WAKE_MAGIC and WAKE_MAGICSECURE. Note that WAKE_FILTER is supportable,
however this will require further discussions and be submitted as a RFC
series later on.
Patch #3 updates the GENET driver to defer to the PHY for Wake-on-LAN if
the PHY supports it, thus allowing the MAC to be powered down to
conserve power.
Changes in v3:
- collected Reviewed-by tags
- explicitly use return 0 in bcm54xx_phy_probe() (Paolo)
Changes in v2:
- introduce PHY_ALWAYS_CALL_SUSPEND and only have the Broadcom PHY
driver set this flag to minimize changes to the suspend flow to only
drivers that need it
- corrected possibly uninitialized variable in bcm54xx_set_wakeup_irq
(Simon)

If available, interrogate the PHY to find out whether we can use it for
Wake-on-LAN. This can be a more power efficient way of implementing
that feature, especially when the MAC is powered off in low power
states.

Add support for WAKE_UCAST, WAKE_MCAST, WAKE_BCAST, WAKE_MAGIC and
WAKE_MAGICSECURE. This is only supported with the BCM54210E and
compatible Ethernet PHYs. Using the in-band interrupt or an out of band
GPIO interrupts are supported.
Broadcom PHYs will generate a Wake-on-LAN level low interrupt on LED4 as
soon as one of the supported patterns is being matched. That includes
generating such an interrupt even if the PHY is operated during normal
modes. If WAKE_UCAST is selected, this could lead to the LED4 interrupt
firing up for every packet being received which is absolutely
undesirable from a performance point of view.
Because the Wake-on-LAN configuration can be set long before the system
is actually put to sleep, we cannot have an interrupt service routine to
clear on read the interrupt status register and ensure that new packet
matches will be detected.
It is desirable to enable the Wake-on-LAN interrupt as late as possible
during the system suspend process such that we limit the number of
interrupts to be handled by the system, but also conversely feed into
the Linux's system suspend way of dealing with interrupts in and around
the points of no return.

A few PHY drivers are currently attempting to not suspend the PHY when
Wake-on-LAN is enabled, however that code is not currently executing at
all due to an early check in phy_suspend().
This prevents PHY drivers from making an appropriate decisions and put
the hardware into a low power state if desired.
In order to allow the PHY drivers to opt into getting their ->suspend
routine to be called, add a PHY_ALWAYS_CALL_SUSPEND bit which can be
set. A boolean that tracks whether the PHY or the attached MAC has
Wake-on-LAN enabled is also provided for convenience.
If phydev::wol_enabled then the PHY shall not prevent its own
Wake-on-LAN detection logic from working and shall not prevent the
Ethernet MAC from receiving packets for matching.

sfc: more flexible encap matches on TC decap rules
This series extends the TC offload support on EF100 to support optionally
matching on the IP ToS and UDP source port of the outer header in rules
performing tunnel decapsulation. Both of these fields allow masked
matches if the underlying hardware supports it (current EF100 hardware
supports masking on ToS, but only exact-match on source port).
Given that the source port is typically populated from a hash of inner
header entropy, it's not clear whether filtering on it is useful, but
since we can support it we may as well expose the capability.

Allow efx_tc_encap_match entries to include a udp_sport and a
udp_sport_mask. As with enc_ip_tos, use pseudos to enforce that all
encap matches within a given <src_ip,dst_ip,udp_dport> tuple have
the same udp_sport_mask.
Note that since we use a single layer of pseudos for both fields, two
matches that differ in (say) udp_sport value aren't permitted to have
different ip_tos_mask, even though this would technically be safe.
Current userland TC does not support setting enc_src_port; this patch
was tested with an iproute2 patched to support it.

Allow efx_tc_encap_match entries to include an ip_tos and ip_tos_mask.
To avoid partially-overlapping Outer Rules (which can lead to undefined
behaviour in the hardware), store extra "pseudo" entries in our
encap_match hashtable, which are used to enforce that all Outer Rule
entries within a given <src_ip,dst_ip,udp_dport> tuple (or IPv6
equivalent) have the same ip_tos_mask.
The "direct" encap_match entry takes a reference on the "pseudo",
allowing it to be destroyed when all "direct" entries using it are
removed.
efx_tc_em_pseudo_type is an enum rather than just a bool because in
future an additional pseudo-type will be added to support Conntrack
offload.

When force-freeing leftover entries from our match_action_ht, call
efx_tc_delete_rule(), which releases all the rule's resources, rather
than open-coding it. The open-coded version was missing a call to
release the rule's encap match (if any).
It probably doesn't matter as everything's being torn down anyway, but
it's cleaner this way and prevents further error messages potentially
being logged by efx_tc_encap_match_free() later on.
Move efx_tc_flow_free() further down the file to avoid introducing a
forward declaration of efx_tc_delete_rule().

Implement ->bpf_bypass_getsockopt proto callback and filter out

socket options from running eBPF hook on them.
SCTP_SOCKOPT_PEELOFF and SCTP_SOCKOPT_PEELOFF_FLAGS options do fd_install(),
and if BPF_CGROUP_RUN_PROG_GETSOCKOPT hook returns an error after success of
the original handler sctp_getsockopt(...), userspace will receive an error
from getsockopt syscall and will be not aware that fd was successfully
installed into a fdtable.
As pointed by Marcelo Ricardo Leitner it seems reasonable to skip
bpf getsockopt hook for SCTP_SOCKOPT_CONNECTX3 sockopt too.
Because internaly, it triggers connect() and if error is masked
then userspace will be confused.

selftests: fcnal: Test SO_DONTROUTE socket option.
The objective is to cover kernel paths that use the RTO_ONLINK flag
in .flowi4_tos. This way we'll be able to safely remove this flag in
the future by properly setting .flowi4_scope instead. With these
selftests in place, we can make sure this won't introduce regressions.
For more context, the final objective is to convert .flowi4_tos to
dscp_t, to ensure that ECN bits don't influence route and fib-rule
lookups (see commit a410a0cf9885 ("ipv6: Define dscp_t and stop taking
ECN bits into account in fib6-rules")).
These selftests only cover IPv4, as SO_DONTROUTE has no effect on IPv6
sockets.
v2:
- Use two different nettest options for setting SO_DONTROUTE either
on the server or on the client socket.
- Use the above feature to run a single 'nettest -B' instance per
test (instead of having two nettest processes for server and
client).

The type of the vlan_proto field is __be16.
And most users of the field use it as such.
In the case of setting or testing the field for the special VLAN_N_VID
value, host byte order is used. Which seems incorrect.
It also seems somewhat odd to store a VLAN ID value in a field that is
otherwise used to store Ether types.
Address this issue by defining BOND_VLAN_PROTO_NONE, a big endian value.
0xffff was chosen somewhat arbitrarily. What is important is that it
doesn't overlap with any valid VLAN Ether types.
I don't believe the problems described above are a bug because
VLAN_N_VID in both little-endian and big-endian byte order does not
conflict with any supported VLAN Ether types in big-endian byte order.

The macsec hardware block supports XPN cipher suites also.
Hence added changes to offload XPN feature. Changes include
configuring SecY policy to XPN cipher suite, Salt and SSCI values.
64 bit packet number is passed instead of 32 bit packet number.

sxgbe_drv_remove() returned zero unconditionally, so it can be converted
to return void without losing anything. The upside is that it becomes
more obvious in its callers that there is no error to handle.

The Microchip ENC28J60 SPI Ethernet driver schedules a work item from
the interrupt handler because accesses to the SPI bus may sleep.
On PREEMPT_RT (which forces interrupt handling into threads) this
old-fashioned approach unnecessarily increases latency because an
interrupt results in first waking the interrupt thread, then scheduling
the work item. So, a double indirection to handle an interrupt.
Avoid by converting the driver to modern threaded interrupt handling.

For 8852CE, there is abnormal state called CMDPSR_FRZTO,
which occasionally happens in some platforms, and could be
found by firmware and fixed in current SER flow, so we add
suppress function to avoid verbose message for this resolved case.

Newer FW re-design SER (syetem error recovery) L1 (level 1) flow.
New L1 flow will expect two extra states before original L1 flow.
* Before:
fw --- M1 --> driver
fw <-- M2 --- driver
fw --- M3 --> driver
fw <-- M4 --- driver
fw --- M5 --> driver
* After:
fw --- pre-M0 --> driver
fw <-- post-M0 --- driver
fw --- M1 --> driver
fw <-- M2 --- driver
fw --- M3 --> driver
fw <-- M4 --- driver
fw --- M5 --> driver
Then before M1, FW gets one more interval to deal with things that FW
should have handled well. To consider backward/forward compatibility,
FW and driver won't change flow from M1 to M5. (only except that halt
trigger control will change a little bit.) So, there will be two differnt
starting points of SER L1.
* old FW: SER L1 starts from M1
* new FW: SER L1 starts from pre-M0
Then, driver adds the new SER L1 entry and also keep the original one
instead of changing it.

RTL8851B keeps almost the same interrupt flow as RTL8852A and RTL8852B.
But, it uses a different bitmask for interrupt indicator of FW HALT C2H.
So, we make a chip judgement in pci when configuring interrupt mask.

U-NII-4 band, i.e 5.9GHz channels, can be supported by chip 8852C, 8852B
and 8851B. But, it is not supported by chip 8852A. Flag support_unii4 is
added in chip info and defined by chip accordingly to indicate that.
We reference this flag of runtime chip to decide whether to register
5.9GHz channels.
After that, we consider if U-NII-4 band is allowed by our regulatory
rule of U-NII-4. If chip::support_unii4 but not regd::allow_unii4,
we stll do not register 5.9GHz channels.
