2023-01-02net: sparx5: Fix reading of the MAC addressHoratiu Vultur1-1/+1
There is an issue with the checking of the return value of 'of_get_mac_address', which returns 0 on success and negative value on failure. The driver interpretated the result the opposite way. Therefore if there was a MAC address defined in the DT, then the driver was generating a random MAC address otherwise it would use address 0. Fix this by checking correctly the return value of 'of_get_mac_address' Fixes: b74ef9f9cb91 ("net: sparx5: Do not use mac_addr uninitialized in mchp_sparx5_probe()") Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: David S.

This type of counter automatically increments it value when the rule is hit. Other VCAP instances have a dedicated counter area outside of the VCAP and in this case the rule must contain the counter id to be able to locate the counter value. In this case there must also be a rule action that updates the counter using the rule id when the rule is hit. The Sparx5 IS2 VCAP uses a dedicated counter area.

2022-10-24net: microchip: sparx5: Adding port keyset config and callback interfaceSteen Hegelund1-0/+345
This provides a default port keyset configuration for the Sparx5 IS2 VCAP where all ports and all lookups in IS2 use the same keyset (MAC_ETYPE) for all types of traffic. This means that no matter what frame type is received on any front port it will generate the MAC_ETYPE keyset in the IS VCAP and any rule in the IS2 VCAP that uses this keyset will be matched against the keys in the MAC_ETYPE keyset. The callback interface used by the VCAP API is populated with Sparx5 specific handler functions that takes care of the actual reading and writing to data to the Sparx5 IS2 VCAP instance. A few functions are also added to the VCAP API to support addition of rule fields such as the ingress port mask and the lookup bit. The IS2 VCAP in Sparx5 is really divided in two instances with lookup 0 and 1 in the first instance and lookup 2 and 3 in the second instance. The lookup bit selects lookup 0 or 3 in the respective instance when it is set.

2022-10-03net: sparx5: Fix return type of sparx5_port_xmit_implNathan Huckleberry2-3/+3
The ndo_start_xmit field in net_device_ops is expected to be of type netdev_tx_t (*ndo_start_xmit)(struct sk_buff *skb, struct net_device *dev). The mismatched return type breaks forward edge kCFI since the underlying function definition does not match the function hook definition. The return type of sparx5_port_xmit_impl should be changed from int to netdev_tx_t.

2022-09-23net: microchip: sparx5: add support for offloading ets qdiscDaniel Machon4-0/+154
Add support for offloading ets qdisc to sparx5 switch. The ets qdisc makes it possible to configure a mix og strict and bandwidth-sharing bands. The ets qdisc must be attached as a root qdisc.

2022-09-23net: microchip: sparx5: add support for offloading tbf qdiscDaniel Machon5-0/+648
Add support for offloading tbf qdisc to sparx5 qdisc. The tbf qdisc makes it possible to attach a shaper on traffic egressing from a port or a queue. Per-port tbf qdiscs are attached as a root qdisc directly and queue tbf qdiscs are attached to one of the classes of a parent qdisc (such as mqprio).

Packets that are not of length divisible by 4 (e.g. 77, 78, 79) would have the checksum included up to next multiple of 4 (a 77 bytes packet would have 3 bytes of ethernet checksum included). The check for the value expects it in host (Little) endian.
