net: marvell: prestera: Propagate nh state from hw to kernel We poll nexthops in HW and call for each active nexthop appropriate neighbour. Also we provide implicity neighbour resolving. For example, user have added nexthop route: # ip route add 5.5.5.5 via 1.1.1.2 But neighbour 1.1.1.2 doesn't exist. In this case we will try to call neigh_event_send, even if there is no traffic. This is useful, when you have add route, which will be used after some time but with a lot of traffic (burst). So, we has prepared, offloaded route in advance.

net: marvell: prestera: implement software MDB entries allocation Define bridge MDB entry (software entry): - entry that get's created upon receiving MDB management events (create/delete), that inherently defines a software entry, which can be enabled (offloaded to the HW) or disabled (removed from HW). This separation is done to achieve a better highlevel management of HW resources - software MDB entry could exist, while it's not necessarily should be configured on the HW. For example: by default, the Linux behavior would not replicate multicast traffic to multicast group members if there's no active multicast router and thus - no actual multicast traffic can be received/sent. So, until multicast router appears on the system no HW configuration should be applied, although SW MDB entries should be tracked. Another example would be altering state of 'multicast enabled' on the bridge: MC_DISABLED should invoke disabling / clearing multicast groups of specified bridge on the HW, yet upon receiving 'multicast enabled' event, driver should reconfigure any existing software MDB groups on the HW. Keeping track of software MDB entries in such way makes it possible to properly react on such events. Define bridge MDB port entry (software entry): - entry that helps keeping track (on software - driver - level) of which bridge mebemer interface joined any give MDB group; Co-developed-by: Yevhen Orlov <yevhen.orlov@plvision.eu> Signed-off-by: Yevhen Orlov <yevhen.orlov@plvision.eu> Signed-off-by: Oleksandr Mazur <oleksandr.mazur@plvision.eu> Signed-off-by: David S.

net: marvell: prestera: add firmware v4.0 support Add firmware (FW) version 4.0 support for Marvell Prestera driver. Major changes have been made to new v4.0 FW ABI to add support of new features, introduce the stability of the FW ABI and ensure better forward compatibility for the future driver vesrions. Current v4.0 FW feature set support does not expect any changes to ABI, as it was defined and tested through long period of time. The ABI may be extended in case of new features, but it will not break the backward compatibility. ABI major changes done in v4.0: - L1 ABI, where MAC and PHY API configuration are split. - ACL has been split to low-level TCAM and Counters ABI to provide more HW ACL capabilities for future driver versions. To support backward support, the addition compatibility layer is required in the driver which will have two different codebase under "if FW-VER elif FW-VER else" conditions that will be removed in the future anyway, So, the idea was to break backward support and focus on more stable FW instead of supporting old version with very minimal and limited set of features/capabilities. Improve FW msg validation: * Use __le64, __le32, __le16 types in msg to/from FW to catch endian mismatch by sparse. * Use BUILD_BUG_ON for structures sent/recv to/from FW.

net: marvell: prestera: Add driver for Prestera family ASIC devices Marvell Prestera 98DX326x integrates up to 24 ports of 1GbE with 8 ports of 10GbE uplinks or 2 ports of 40Gbps stacking for a largely wireless SMB deployment. The current implementation supports only boards designed for the Marvell Switchdev solution and requires special firmware. The core Prestera switching logic is implemented in prestera_main.c, there is an intermediate hw layer between core logic and firmware. It is implemented in prestera_hw.c, the purpose of it is to encapsulate hw related logic, in future there is a plan to support more devices with different HW related configurations. This patch contains only basic switch initialization and RX/TX support over SDMA mechanism. Currently supported devices have DMA access range <= 32bit and require ZONE_DMA to be enabled, for such cases SDMA driver checks if the skb allocated in proper range supported by the Prestera device. Also meanwhile there is no TX interrupt support in current firmware version so recycling work is scheduled on each xmit. Port's mac address is generated from the switch base mac which may be provided via device-tree (static one or as nvme cell), or randomly generated. This is required by the firmware.
