net/mlx5: Use flow steering infrastructure for mlx5_en

2015-12-12T05:15:24Z

Expose the new flow steering API and remove the old one. Few changes are required: 1. The Ethernet flow steering follows the existing implementation, but uses the new steering API. The old flow steering implementation is removed. 2. Move the E-switch FDB management to use the new API. 3. When driver is loaded call to mlx5_init_fs which initialize the flow steering tree structure, open namespaces for NIC receive and for E-switch FDB. 4. Call to mlx5_cleanup_fs when the driver is unloaded. Signed-off-by: Maor Gottlieb Signed-off-by: Moni Shoua Signed-off-by: Matan Barak Signed-off-by: Saeed Mahameed Signed-off-by: David S. Miller

net/mlx5: E-Switch, Add SR-IOV (FDB) support

2015-12-03T17:08:46Z

Enabling E-Switch SRIOV for nvfs+1 vports. Create E-Switch FDB for L2 UC/MC mac steering between VFs/PF and external vport (Uplink). FDB contains forwarding rules such as: UC MAC0 -> vport0(PF). UC MAC1 -> vport1. UC MAC2 -> vport2. MC MACX -> vport0, vport2, Uplink. MC MACY -> vport1, Uplink. For unmatched traffic FDB has the following default rules: Unmached Traffic (src vport != Uplink) -> Uplink. Unmached Traffic (src vport == Uplink) -> vport0(PF). FDB rules population: Each NIC vport (VF) will notify E-Switch manager of its UC/MC vport context changes via modify vport context command, which will be translated to an event that will be handled by E-Switch manager (PF) which will update FDB table accordingly.

net/mlx5: Ethernet resource handling files

2015-05-31T01:24:39Z

This patch contains the resource handling files: - flow_table.c: This file contains the code to handle the low level API to configure hardware flow table. It is separated from the flow_table_en.c, because it will be used in the future by Raw Ethernet QP in mlx5_ib too. - en_flow_table.[ch]: Ethernet flow steering handling. The flow table object contain a mapping between flow specs and TIRs. This mechanism will be used also to configure e-switch in the future, when SR-IOV support will be added. - transobj.[ch] - Low level functions to create/modify/destroy the transport objects: RQ/SQ/TIR/TIS - vport.[ch] - Handle attributes of a virtual port (vPort) in the embedded switch. Currently this switch is a passthrough, until SR-IOV support will be added. Signed-off-by: Amir Vadai Signed-off-by: David S. Miller
