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.

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.

When using the kernel datapath, the upcall don't
include skb hash info relatived. That will introduce
some problem, because the hash of skb is important
in kernel stack. For example, VXLAN module uses
it to select UDP src port. The tx queue selection
may also use the hash in stack.

Hash is computed in different ways. Hash is random
for a TCP socket, and hash may be computed in hardware,
or software stack. Recalculation hash is not easy.

Hash of TCP socket is computed:
tcp_v4_connect
    -> sk_set_txhash (is random)

__tcp_transmit_skb
    -> skb_set_hash_from_sk

There will be one upcall, without information of skb
hash, to ovs-vswitchd, for the first packet of a TCP
session. The rest packets will be processed in Open vSwitch
modules, hash kept. If this tcp session is forward to
VXLAN module, then the UDP src port of first tcp packet
is different from rest packets.

TCP packets may come from the host or dockers, to Open vSwitch.
To fix it, we store the hash info to upcall, and restore hash
when packets sent back.

PTP clock source for SJA1105 tc-taprio offload

This series makes the IEEE 802.1Qbv egress scheduler of the sja1105
switch use a time reference that is synchronized to the network. This
enables quite a few real Time Sensitive Networking use cases, since in
this mode the switch can offer its clients a TDMA sort of access to the
network, and guaranteed latency for frames that are properly scheduled
based on the common PTP time.

The driver needs to do a 2-part activity:
- Program the gate control list into the static config and upload it
  over SPI to the switch (already supported)
- Write the activation time of the scheduler (base-time) into the
  PTPSCHTM register, and set the PTPSTRTSCH bit.
- Monitor the activation of the scheduler at the planned time and its
  health.

Ok, 3 parts.

The time-aware scheduler cannot be programmed to activate at a time in
the past, and there is some logic to avoid that.

PTPCLKCORP is one of those "black magic" registers that just need to be
written to the length of the cycle. There is a 40-line long comment in

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.
