Remove the assert from the callback priv lookup function since it does
not require RTNL lock and is already protected by flow_indr_block_lock.
This will avoid warnings from being emitted to dmesg if the driver
registers its callback after an ingress qdisc was created for a
netdevice.
The warnings started after the following patch was merged:

Add in the logic to update flow stats. The flow stats from the nfp
is saved in the flow_pay struct, which is associated with the final
merged flow. This saves deltas however, so once read it needs to
be cleared. However the flow stats requests from the kernel is
from the other side of the chain, and a single tc flow from
the kernel can be merged into multiple other tc flows to form
multiple offloaded flows. This means that all linked flows
needs to be updated for each stats request.

Expose and refactor the match compilation functions so that they
can be invoked externally. Also update the functions so they can
be called multiple times with the results OR'd together. This is
applicable for the flows-merging scenario, in which there could be
overlapped and non-conflicting match fields. This will be used
in upcoming conntrack patches. This is safe to do in the in the
single call case as well since both unmasked_data and mask_data
gets initialised to 0.

Pull fallthrough fixes from Gustavo Silva:
"This fixes many fall-through warnings when building with Clang and
-Wimplicit-fallthrough, and also enables -Wimplicit-fallthrough for
Clang, globally.
It's also important to notice that since we have adopted the use of
the pseudo-keyword macro fallthrough, we also want to avoid having
more /* fall through */ comments being introduced. Contrary to GCC,
Clang doesn't recognize any comments as implicit fall-through markings
when the -Wimplicit-fallthrough option is enabled.
So, in order to avoid having more comments being introduced, we use
the option -Wimplicit-fallthrough=5 for GCC, which similar to Clang,
will cause a warning in case a code comment is intended to be used as
a fall-through marking. The patch for Makefile also enforces this.
We had almost 4,000 of these issues for Clang in the beginning, and
there might be a couple more out there when building some
architectures with certain configurations. However, with the recent
fixes I think we are in good shape and it is now possible to enable
the warning for Clang"

The current location of the callback delete can lead to a race
condition where deleting the callback requires a write_lock on
the nf_table, but at the same time another thread from netfilter
could have taken a read lock on the table before trying to offload.
Since the driver is taking a rtnl_lock this can lead into a deadlock
situation, where the netfilter offload will wait for the cls_flower
rtnl_lock to be released, but this cannot happen since this is
waiting for the nf_table read_lock to be released before it can
delete the callback.
Solve this by completely removing the nf_flow_table_offload_del_cb
call, as this will now be cleaned up by act_ct itself when cleaning
up the specific nf_table.

Implement code to add and remove nft flows to the relevant list.
Registering and deregistering the callback function for the nft
table is quite complicated. The safest is to delete the callback
on the removal of the last pre_ct flow. This is because if this
is also the latest pre_ct flow in software it means that this
specific nft table will be freed, so there will not be a later
opportunity to do this. Another place where it looks possible
to delete the callback is when the last nft_flow is deleted,
but this happens under the flow_table lock, which is also taken
when deregistering the callback, leading to a deadlock situation.
This means the final solution here is to delete the callback
when removing the last pre_ct flow, and then clean up any
remaining nft_flow entries which may still be present, since
there will never be a callback now to do this, leaving them
orphaned if not cleaned up here as well.

Add merging of pre/post_ct flow rules into the tc_merge table.
Pre_ct flows needs to be merge with post_ct flows and vice versa.
This needs to be done for all flows in the same zone table, as well
as with the wc_zone_table, which is for flows masking out ct_zone
info.
Cleanup is happening when all the tables are cleared up and prints
a warning traceback as this is not expected in the final version.
At this point we are not actually returning success for the offload,
so we do not get any delete requests for flows, so we can't delete
them that way yet. This means that cleanup happens in what would
usually be an exception path.

flow actually reaches the firmware, during which we may get duplicate
merge hints if there're more than one packet that hit the pre-merged

Avoid the duplicate merge by using hash table to store the sub_flows

pre_tun_rule flows does not follow the usual add-flow path, instead
they are used to update the pre_tun table on the firmware. This means
that if the mask-id gets allocated here the firmware will never see the
"NFP_FL_META_FLAG_MANAGE_MASK" flag for the specific mask id, which
triggers the allocation on the firmware side. This leads to the firmware
mask being corrupted and causing all sorts of strange behaviour.

The indirect block cleanup may cause control messages to be sent
if offloaded flows are present. However, by the time the flower app
cleanup callback is called txbufs are no longer available and attempts
to send control messages result in a NULL-pointer dereference in
nfp_ctrl_tx_one().
This problem may be resolved by moving the indirect block cleanup
to the stop callback, where txbufs are still available.

Fix an issue where the driver wrongly detected ipv6 neighbour updates
from the NFP as corrupt. Add a reserved field on the kernel side so
it is similar to the ipv4 version of the struct and has space for the
extra bytes from the card.

Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.

When both the driver and the firmware supports QinQ the flow key
structure that is send to the firmware is updated as the old
method of matching on VLAN did not allow for space to add another
VLAN tag. VLAN flows can now also match on the tpid field, not
constrained to just 0x8100 as before.

Previously, shared blocks were only relevant for the pseudo-qdiscs ingress
and clsact. Recently, a qevent facility was introduced, which allows to
bind blocks to well-defined slots of a qdisc instance. RED in particular
got two qevents: early_drop and mark. Drivers that wish to offload these
blocks will be sent the usual notification, and need to know which qdisc it
is related to.
To that end, extend flow_block_offload with a "sch" pointer, and initialize
as appropriate. This prompts changes in the indirect block facility, which
now tracks the scheduler in addition to the netdevice. Update signatures of
several functions similarly.
