2021-12-20net: lan966x: Add support to offload the forwarding.Horatiu Vultur5-2/+354
This patch adds basic support to offload in the HW the forwarding of the frames. The driver registers to the switchdev callbacks and implements the callbacks for attributes SWITCHDEV_ATTR_ID_PORT_STP_STATE and SWITCHDEV_ATTR_ID_BRIDGE_AGEING_TIME. It is not allowed to add a lan966x port to a bridge that contains a different interface than lan966x. Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: David S.

2021-12-20mlxsw: core: Extend devlink health reporter with new events and parametersDanielle Ratson1-0/+131
Extend the devlink health reporter registered by mlxsw to report new health events and their related parameters. These are meant to aid in debugging of hardware / firmware issues. Beside the test event ('MLXSW_REG_MFDE_EVENT_ID_TEST') that is triggered following the devlink health 'test' sub-command, the new events are used to report the triggering of asserts in firmware code ('MLXSW_REG_MFDE_EVENT_ID_FW_ASSERT') and hardware issues ('MLXSW_REG_MFDE_EVENT_ID_FATAL_CAUSE'). Each event is accompanied with a severity parameter and per-event parameters that are meant to help root cause the detected issue.

2021-12-20bnx2x: Invalidate fastpath HSI version for VFsManish Chopra1-2/+11
Commit 0a6890b9b4df ("bnx2x: Utilize FW 7.13.15.0.") added validation for fastpath HSI versions for different client init which was not meant for SR-IOV VF clients, which resulted in firmware asserts when running VF clients with different fastpath HSI version. This patch along with the new firmware support in patch #1 fixes this behavior in order to not validate fastpath HSI version for the VFs. Fixes: 0a6890b9b4df ("bnx2x: Utilize FW 7.13.15.0.")

Fix the false positive suspend error that may occur on mt7921s with enlarging mcu timeout value. The reason why we have to enlarge mcu timeout from HZ / 3 to HZ is we should consider the additional overhead caused by running concurrently with btmtksdio (a MT7921 bluetooth SDIO driver) that would compete for the same SDIO bus in process context to complete the suspend procedure.
