* mlxsw: spectrum_acl: Add replace rule action operationNir Dotan2018-12-121-0/+33
| | | | | | | | | | | | | | | | | Multicast routes actions may be updated after creation. An example for that is an addition of an egress interface to an existing route. So far, as tc flower API dictated, ACL rules were either created or deleted. Since multicast routes in Spectrum-2 are written to ACL as any rule, it is required to allow the update of a rule's action as it may change. Add methods and operations to support updating rule's action. This is supported only for Spectrum-2.

* mlxsw: spectrum_acl: Start using A-TCAMIdo Schimmel2018-07-261-3/+11
| | | | | | | | | | | | | | Now that all the pieces are in place we can start using the A-TCAM instead of only using the C-TCAM. This allows for much higher scale and better performance (to be improved further by follow-up patch sets). Perform the integration with the A-TCAM and the eRP core by reverting the changes introduced by "mlxsw: spectrum_acl: Enable C-TCAM only mode in eRP core" and add calls from the C-TCAM code into the eRP core.

* mlxsw: spectrum_acl: Pass C-TCAM region and entry to insert functionIdo Schimmel2018-07-261-10/+11
| | | | | | | | | | | | | When A-TCAM will be used together with C-TCAM, the C-TCAM code will need to call into the eRP core in order to get an eRP for an inserted entry. The eRP core takes an A-TCAM region as one of its arguments, so pass the C-TCAM region to the insertion function which will later allow us to derive the A-TCAM region, given it contains the C-TCAM one.

* mlxsw: spectrum_acl: Allow encoding a partial keyIdo Schimmel2018-07-261-1/+4
| | | | | | | | | | | | | | | | | | | | When working with 12 key blocks in the A-TCAM, rules are split into two records, which constitute two lookups. The two records are linked using a "large entry key ID". The ID is assigned to key blocks 6 to 11 and resolved during the first lookup. The second lookup is performed using the ID and the remaining key blocks. Allow encoding a partial key so that it can be later used to check if an ID can be reused. This is done by adding two arguments to the existing encode function that specify the range of the block indexes we would like to encode. The key and mask arguments become optional, as we will not need to encode both of them all the time.

* mlxsw: spectrum_acl: Implement priority setting for rules inserted to TCAMJiri Pirko2018-07-101-4/+13
| | | | | | | | | | | | | | For Spectrum-2, we need to insert priority to C-TCAM because HW needs that info in order to correctly process scenarios where rules are in both C-TCAM and A-TCAM. So extend the mlxsw_sp_acl_ctcam_entry_add() args to accept indication if priority needs to be filled up and implement the priority computation and fill-up.

To allow easy and clean Spectrum-2 implementation for things that differ from Spectrum, split the existing ACL TCAM code 3 ways: 1) common code that calls Spectrum/Spectrum-2 specific ops 2) Spectrum ops implementations 3) common C-TCAM code that is going to be shared between Spectrum and Spectrum-2 implementations Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: David S.
