* | mlxsw: spectrum: Set port's mode according to FID mappingsIdo Schimmel2017-05-264-28/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently transition the port to "Virtual mode" upon the creation of its first VLAN upper, as we need to classify incoming packets to a FID using {Port, VID} and not only the VID. However, it's more appropriate to transition the port to this mode when the {Port, VID} are actually mapped to a FID. Either during the enslavement of the VLAN upper to a VLAN-unaware bridge or the configuration of a router port. Do this change now in preparation for the introduction of the FID core, where this operation will be encapsulated. To prevent regressions, this patch also explicitly configures an OVS slave to "Virtual mode". Otherwise, a packet that didn't hit an ACL rule could be classified to an existing FID based on a global VID-to-FID mapping, thus not incurring a FID mis-classification, which would otherwise trap the packet to the CPU to be processed by the OVS daemon.

| | | | | | | | | | | | | | | | | | | | | | | | Implement the port enable/disable callbacks, which enable/disable the SERDES interfaces, if applicable. This should save a bit of power/heat. We also need to enable SERDES on CPU and DSA ports, so keep the existing call to the op, but make it conditional. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

The culprit is octeon_mbox_write() who ignores an ack timeout condition; it just keeps unconditionally writing all elements of mbox_cmd->data[] even when the other side is not ready for them.

This allows using the Innova card as a regular NIC, by detecting the FPGA capability bit, and verifying its load state before initializing ConnectX interfaces. Also detect FPGA fatal runtime failures and enter error state if they ever happen. All new FPGA-related logic is placed in its own subdirectory 'fpga', which may be built by selecting CONFIG_MLX5_FPGA. This prepares for further support of various Innova features in later patchsets. Additional details about hardware architecture will be provided as more features get submitted.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce new function for entering bad-health state. This function will be called from FPGA-related logic in a later patch from asynchronous event (IRQ) context, for that we change the spin lock to an IRQ-safe one.

This made the mlx5_vzalloc function useless, so let's remove it. Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
