Traffic for a CGX mapped NIXLF can be stopped by disabling entries
in NPC MCAM or by configuring CGX and mailbox messages exist for the
two options. If traffic is stopped at CGX then VFs of that PF are
also effected hence CGX traffic should be started/stopped by
tracking all the users of it. This patch implements that CGX users
tracking. CGX is also configured along with NPC if required.
Also removed a check which mandates even number of LBK VFs.

A config option is added to disable caching of dynamic entries
like SQEs and stack pages. Also locks down all HW contexts in NDC,
preventing them from being evicted.
This option is useful when the queue count is large and there are
huge NDC cache misses. It's trade off between SQ context misses and
dynamically changing entries like SQE and stack page pointers.

Ingress packet replication support has been added to 96xx B0
silicon. This patch enables using that feature to replicate
ingress broadcast packets to PF and it's VFs.
Also fixed below issues
- VFs can also install NPC MCAM entry to forward broadcast pkts.
Otherwise, unless PF's interface is UP, VFs will not receive
bcast packets.
- NPC MCAM entry is disabled when PF and all it's VFs are down.
- Few corner cases in installing multicast entry list.

CN96xx initial silicon doesn't support all features pertaining to
NIX transmit scheduling and shaping.
- It supports a fixed topology of 1:1 mapped transmit
limiters at all levels.
- Supports DWRR only at SMQ/MDQ and TL1.
- Doesn't support shaping and coloring.
This patch adds HW capability structure by which each variant
and skew of silicon can be differentiated by their supported
features. And adds support for A0 silicon's transmit scheduler
capabilities or rather limitations.

Writing into NPC MCAM1 and MCAM0 registers are suppressed if
they happened to form a reserved combination. Hence
clear and disable MCAM entries before update.
For HRM:
[CAM(1)]<n>=1, [CAM(0)]<n>=1: Reserved.
The reserved combination is not allowed. Hardware suppresses any
write to CAM(0) or CAM(1) that would result in the reserved combination for
any CAM bit.

Updated NPC KPU packet parsing profile with support for following
- Fragmentation support for IPv4 IPv6 outer header
- NIX instruction header support
- QinQ with TPID of 0x8100 as non inner most vlan tag, as legacy
network equipments still generate QinQ packets with this configuration.
- To better support RSS for tunnelled packets, udp based tunnel
protocols such as vxlan, vxlan-gpe, geneve and gtpu are now
captured into a separate layer E. Consequently, the inner
packet headers are pushed one layer down to LF, LG, and LH
accordingly.
- Support for rfc7510 mpls in udp. Up to 4 MPLS labels can be parsed
and captured in one layer LE.
- Parser support for DSA, extended DSA and eDSA tags right after
ethernet header by Marvell SOHO and Falcon switches. For extended
DSA and eDSA tags, a special PKIND of 62 is used, as these tags don't
contain a tpid field.
- Higig2 protocol header parsing support, added a NPC_LT_LA_HIGIG2_ETHER
for a combined header of HIGIG2 and Ethernet. Add a
NPC_LT_LA_IH_NIX_HIGIG2_ETHER for a combined header of nix_ih,
HIGIG2 and Ethernet on egress side. Also added 2 upper flags in LA to
indicate the presence of nix_ih and HIGIG2.
Other changes include
- IPv4.TTL==0 IPv6.HLIM==0 check
- Per RFC 1858, mark fragment offset == 1 as error
- TCP invalid flags check
- Separate error codes for outer and inner IPv4 checksum errors.
- Fix a parser error when KPU parses incoming IPSec ESP and AH packets
- NPC vtag capture/strip hardware expect tag pointer to point to
tpid/ethertype instead of tci. So move lb_ptr to point to tpid/ethertype.
- Fix npc parser error when parsing udp packets that don't have any payload.
- For a single MCAM entry to match on packets with one or stacked vlan tags
combine NPC_LT_LB_STAG and NPC_LT_LB_QINQ to NPC_LT_LB_STAG_QINQ.
- NVGRE to have a separate ltype LD_NVGRE instead of combined with LD_GRE.
- Reserve top LD/LTYPEs to support custom KPU profile fields.

Added a new mailbox API which goes through all responses
to check their IDs and response codes.
Also added logic to prevent queuing multiple works to
process the same mailbox message. This scenario happens
when AF is processing a PF's request and menawhile PF
sends ACK to AF sent UP message, then mbox_hdr->num_msgs
in the PF->AF DOWN mbox region will be nonzero and AF
will end up processing PF's request again. This is fixed
by taking a backup of num_msgs counter and clearing the
same in the mbox region before scheduling work.

NDC is a data cache unit which caches NPA and NIX block's
aura/pool/RQ/SQ/CQ/etc contexts to reduce number of costly
DRAM accesses.
This patch adds support to dump cache's performance stats
like cache line hit/miss counters, average cycles taken for
accessing cached and non-cached data. This will help in
checking if NPA/NIX context reads/writes are having NDC cache
misses which inturn might effect performance.

Previously, hns3 driver just directly send specific setting bit
and mask bits of MAC VLAN switch parameter to the firmware, it
can not be compatible with the old firmware, because the old one
ignores mask bits and covers all bits with new setting bits.
So when running with old firmware, the communication between PF
and VF will fail after resetting or configuring spoof check, since
they will do the MAC VLAN switch parameter configuration.
This patch fixes this problem by reading switch parameter firstly,
then just modifies the corresponding bit and sends it to firmware.

The "state machine" is a workqueue invoked after each manipulation
command on the PTP clock (reset, adjust time, set time, adjust
frequency) which checks over the state of the time-aware scheduler.
So it is not monitored periodically, only in reaction to a PTP command
typically triggered from a userspace daemon (linuxptp). Otherwise there
is no reason for things to go wrong.
Now that the timecounter/cyclecounter has been replaced with hardware
operations on the PTP clock, the TAS Kconfig now depends upon PTP and
the standalone clocksource operating mode has been removed.

The SDIO HW reset procedure in mwifiex_sdio_card_reset_work() is broken,
when the SDIO card is shared with another SDIO func driver. This is the
case when the Bluetooth btmrvl driver is being used in combination with
mwifiex. More precisely, when mwifiex_sdio_card_reset_work() runs to resets
the SDIO card, the btmrvl driver doesn't get notified about it. Beyond that
point, the btmrvl driver will fail to communicate with the SDIO card.
This is a generic problem for SDIO func drivers sharing an SDIO card, which
are about to be addressed in subsequent changes to the mmc core and the
mmc_hw_reset() interface. In principle, these changes means the
mmc_hw_reset() interface starts to return 1 if the are multiple drivers for
the SDIO card, as to indicate to the caller that the reset needed to be
scheduled asynchronously through a hotplug mechanism of the SDIO card.
Let's prepare the mwifiex driver to support the upcoming new behaviour of
mmc_hw_reset(), which means extending the mwifiex_sdio_card_reset_work() to
support the asynchronous SDIO HW reset path. This also means, we need to
allow the ->remove() callback to run, without waiting for the FW to be
loaded. Additionally, during system suspend, mwifiex_sdio_suspend() may be
called when a reset has been scheduled, but waiting to be executed. In this
scenario let's simply return -EBUSY to abort the suspend process, as to
allow the reset to be completed first.

Send EAPOL frames via control path so they can be treated in a different
way rather than normal data frames. In this case EAPOLs are sent with
higher priority and with disabled aggregation and encryption. Besides,
all devices benefit from sending EAPOL frames via high priority path,
so move the functionality from chip specific to common code.
