net: mscc: ocelot: Hardware ofload for tc flower filter

2019-06-02T20:49:49Z

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 Signed-off-by: David S. Miller

net: mscc: ocelot: Add support for tcam

2019-06-02T20:49:49Z

Add ACL support using the TCAM. Using ACL it is possible to create rules in hardware to filter/redirect frames. Signed-off-by: Horatiu Vultur Signed-off-by: David S. Miller

net: mscc: ocelot: Implement port policers via tc command

2019-05-30T04:37:49Z

Hardware offload of matchall classifier and police action are now supported via the tc command. Supported police parameters are: rate and burst. Example: Add: tc qdisc add dev eth3 handle ffff: ingress tc filter add dev eth3 parent ffff: prio 1 handle 2 \ matchall skip_sw \ action police rate 100Mbit burst 10000 Show: tc -s -d qdisc show dev eth3 tc -s -d filter show dev eth3 ingress Delete: tc filter del dev eth3 parent ffff: prio 1 tc qdisc del dev eth3 handle ffff: ingress Signed-off-by: Joergen Andreasen Signed-off-by: David S.

net: mscc: Add initial Ocelot switch support

2018-05-15T20:41:15Z

Add a driver for Microsemi Ocelot Ethernet switch support. This makes two modules: mscc_ocelot_common handles all the common features that doesn't depend on how the switch is integrated in the SoC. Currently, it handles offloading bridging to the hardware. ocelot_io.c handles register accesses. This is unfortunately needed because the register layout is packed and then depends on the number of ports available on the switch. The register definition files are automatically generated. ocelot_board handles the switch integration on the SoC and on the board. Frame injection and extraction to/from the CPU port is currently done using register accesses which is quite slow. DMA is possible but the port is not able to absorb the whole switch bandwidth.
