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.

* net: microchip: vcap api: Use src and dst chain id to chain VCAP lookupsSteen Hegelund2023-01-162-54/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds both the source and destination chain id to the information kept for enabled port lookups. This allows enabling and disabling a chain of lookups by walking the chain information for a port. This changes the way that VCAP lookups are enabled from userspace: instead of one matchall rule that enables all the 4 Sparx5 IS2 lookups, you need a matchall rule per lookup. In practice that is done by adding one matchall rule in chain 0 to goto IS2 Lookup 0, and then for each lookup you add a rule per lookup (low priority) that does a goto to the next lookup chain. Examples: If you want IS2 Lookup 0 to be enabled you add the same matchall filter as before: tc filter add dev eth12 ingress chain 0 prio 1000 handle 1000 matchall \ skip_sw action goto chain 8000000 If you also want to enable lookup 1 to 3 in IS2 and chain them you need to add the following matchall filters: tc filter add dev eth12 ingress chain 8000000 prio 1000 handle 1000 \ matchall skip_sw action goto chain 8100000 tc filter add dev eth12 ingress chain 8100000 prio 1000 handle 1000 \ matchall skip_sw action goto chain 8200000 tc filter add dev eth12 ingress chain 8200000 prio 1000 handle 1000 \ matchall skip_sw action goto chain 8300000 Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: Steen Hegelund <steen.hegelund@microchip.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | Currently whenever a new rule id is generated, it picks up the next number bigger than previous id. So it would always be 1, 2, 3, etc. When the rule with id 1 will be deleted and a new rule will be added, it will have the id 4 and not id 1. In theory this can be a problem if at some point a rule will be added and removed ~0 times. Then no more rules can be added because there are no more ids. Change this such that when a new rule is added, search for an empty rule id starting with value of 1 as value 0 is reserved.
