2020-03-30net: mscc: ocelot: add action of police on vcap_is2Xiaoliang Yang
Ocelot has 384 policers that can be allocated to ingress ports, QoS classes per port, and VCAP IS2 entries. ocelot_police.c supports to set policers which can be allocated to police action of VCAP IS2. We allocate policers from maximum pol_id, and decrease the pol_id when add a new vcap_is2 entry which is police action.

2020-03-03net: mscc: ocelot: simplify tc-flower offload structuresVladimir Oltean
The ocelot tc-flower offload binds a second flow block callback (apart from the one for matchall) just because it uses a different block private structure (ocelot_port_private for matchall, ocelot_port_block for flower). But ocelot_port_block just appears to be boilerplate, and doesn't help with anything in particular at all, it's just useless glue between the (global!) struct ocelot_acl_block *block pointer, and a per-netdevice struct ocelot_port_private *priv. So let's just simplify that, and make struct ocelot_port_private be the private structure for the block offload. This makes us able to use the same flow callback as in the case of matchall. This also reveals that the struct ocelot_acl_block *block is used rather strangely, as mentioned above: it is defined globally, allocated at probe time, and freed at unbind time. So just move the structure to the main ocelot structure, which gives further opportunity for simplification. Also get rid of backpointers from struct ocelot_acl_block and struct ocelot_ace_rule back to struct ocelot, by reworking the function prototypes, where necessary, to use a more DSA-friendly "struct ocelot *ocelot, int port" format. And finally, remove the debugging prints that were added during development, since they provide no useful information at this point.

2020-03-03net: mscc: ocelot: make ocelot_ace_rule support multiple portsYangbo Lu
The ocelot_ace_rule is port specific now. Make it flexible to be able to support multiple ports too.

2019-11-11net: mscc: ocelot: separate net_device related items out of ocelot_portVladimir Oltean
The ocelot and ocelot_port structures will be used by a new DSA driver, so the ocelot_board.c file will have to allocate and work with a private structure (ocelot_port_private), which embeds the generic struct ocelot_port. This is because in DSA, at least one interface does not have a net_device, and the DSA driver API does not interact with that anyway. The ocelot_port structure is equivalent to dsa_port, and ocelot to dsa_switch. The members of ocelot_port which have an equivalent in dsa_port (such as dp->vlan_filtering) have been moved to ocelot_port_private. We want to enforce the coding convention that "ocelot_port" refers to the structure, and "port" refers to the integer index. One can retrieve the structure at any time from ocelot->ports[port]. The patch is large but only contains variable renaming and mechanical movement of fields from one structure to another.

2019-07-09drivers: net: use flow block APIPablo Neira Ayuso
This patch updates flow_block_cb_setup_simple() to use the flow block API. Several drivers are also adjusted to use it. This patch introduces the per-driver list of flow blocks to account for blocks that are already in use. Remove tc_block_offload alias.

2019-06-02net: mscc: ocelot: Hardware ofload for tc flower filterHoratiu Vultur
Hardware offload of port filtering are now supported via tc command using flower filter. ACL rules are used to enable the hardware offload. The following keys are supported: vlan_id vlan_prio dst_mac/src_mac for non IP frames dst_ip/src_ip dst_port/src_port The following actions are supported: trap drop These filters are supported only on the ingress schedulare. Add: tc qdisc add dev eth3 ingress tc filter ad dev eth3 parent ffff: ip_proto ip flower \ ip_proto tcp dst_port 80 action drop Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: David S.
