The vcap_admin structures in vcap_api_next_lookup_advanced_test()
take several hundred bytes of stack frame, but when CONFIG_KASAN_STACK
is enabled, each one of them also has extra padding before and after
it, which ends up blowing the warning limit:
In file included from drivers/net/ethernet/microchip/vcap/vcap_api.c:3521:
drivers/net/ethernet/microchip/vcap/vcap_api_kunit.c: In function 'vcap_api_next_lookup_advanced_test':
drivers/net/ethernet/microchip/vcap/vcap_api_kunit.c:1954:1: error: the frame size of 1448 bytes is larger than 1400 bytes [-Werror=frame-larger-than=]
1954 | }
Reduce the total stack usage by replacing the five structures with
an array that only needs one pair of padding areas.

The rule counter must be cleared when creating a new rule, even if the VCAP
lookup is currently disabled.
This ensures that rules located in VCAPs that use external counters (such
as Sparx5 IS2 and ES0) will have their counter reset even if the VCAP
lookup is not enabled at the moment.

This supports that individual rules are enabled and disabled via chain
information.
This is done by keeping disabled rules in the VCAP list (cached) until they
are enabled, and only at this time are the rules written to the VCAP HW.

This changes the way the chain information verified when adding a new tc
flower filter.
When adding a flower filter it is now checked that the filter contains a
goto action to one of the IS2 VCAP lookups, except for the last lookup
which may omit this goto action.
It is also checked if you attempt to add multiple matchall filters to
enable the same VCAP lookup. This will be rejected.

This changes the VCAP lookups state to always be enabled so that it is
possible to add "internal" VCAP rules that must be available even though
the user has not yet enabled the VCAP chains via a TC matchall filter.
The API callback to enable and disable VCAP lookups is therefore removed.
