Since we currently do not support the offloading of 802.1D bridges, we need to be able to let the device know it should not learn MAC addresses on specific {Port, VID} pairs. Add the SPVMLR register, which controls the learning enablement of {Port, VID} pairs.

Packets destined to offloaded netdevs will be classified to FIDs in the device and flooded in case of BUM. The flooding table used is of type FID-offset, which allows one to create different flooding domains for different FIDs and specify the offset in the flooding table for each FID (not necessarily equal to FID or VID). Add support for this flooding table type, by exposing the configuration of the number of tables from this type and their size.

In the newly introduced Spectrum switch ASIC, packets destined to not offloaded netdevs will be classified to special FIDs (vFIDs) in the device and flooded to the CPU port. The flooding table used is of type per-FID, which allows one to create different flooding domains for different vFIDs. While using a simple single-entry flood table is certainly sufficient at this point, we do plan to offload 802.1D bridges involving VLAN interfaces, thus making this change necessary. Add support for this flooding table type, by exposing the configuration of the number of tables from this type and their size.

Previously, we trapped flooded and control packets using the same trap group. This can cause flooded packets to overflow the PCI bus and prevent control packets (e.g. STP, LACP) from getting to the CPU. Solve this by splitting the RX trap group to RX and control, which allows us to configure a policer on the first, thereby preventing it from overflowing the PCI bus.

The Host Trap Group Table (HTGT) register configures trap groups, which are populated with trap IDs using the Host PacKet Trap (HPKT) register. However, a trap ID can only be present inside one trap group (the last configured). Instead of passing both the trap group and ID for the function that packs HPKT, pass only the trap ID and derive from it the trap group.

由 Jack Morgenstein 提交于
By design, when no default MAC addresses are set in the Hypervisor for VFs, the VFs are passed zero-macs. When such a MAC is received by the VF, it generates a random MAC address and registers that MAC address with the Hypervisor. This random mac generation is currently done in the mlx4_en module. There is a problem, though, if the mlx4_ib module is loaded by a VF before the mlx4_en module. In this case, for RoCE, mlx4_ib will see the un-replaced zero-mac and register that zero-mac as part of QP1 initialization. Having a zero-mac in the port's MAC table creates problems for a Baseboard Management Console. The BMC occasionally sends packets with a zero-mac destination MAC. If there is a zero-mac present in the port's MAC table, the FW will send such BMC packets to the host driver rather than to the wire, and BMC will stop working. To address this problem, we move the replacement of zero-mac addresses with random-mac addresses to procedure mlx4_slave_cap(), which is part of the driver startup for VFs, and is before activation of mlx4_ib and mlx4_en. As a result, zero-mac addresses will never be registered in the port MAC table by the driver. In addition, when mlx4_en does initialize the net device, it needs to set the NET_ADDR_RANDOM flag in the netdev structure if the address was randomly generated. This is done so that udev on the VM does not create a new device name after each VF probe (VM boot and such). To accomplish this, we add a per-port flag in mlx4_dev which gets set whenever mlx4_core replaces a zero-mac with a randomly-generated mac. This flag is examined when mlx4_en initializes the net-device.

This patch implement the pci_error_handlers for mlx5_core which allow the driver to recover from PCI error. Once an error is detected in the PCI, the mlx5_pci_err_detected is called and it: 1) Marks the device to be in 'Internal Error' state. 2) Dispatches an event to the mlx5_ib to flush all the outstanding cqes with error. 3) Returns all the on going commands with error. 4) Unloads the driver. Afterwards, the FW is reset and mlx5_pci_slot_reset is called and it enables the device and restore it's pci state. If the later succeeds, mlx5_pci_resume is called, and it loads the SW stack.
