net/mlx5: Introducing E-Switch and l2 table
E-Switch is the software entity that represents and manages ConnectX4 inter-HCA ethernet l2 switching. E-Switch has its own Virtual Ports, each Vport/vNIC/VF can be connected to the device through a vport of an e-switch. Each e-switch is managed by one vNIC identified by HCA_CAP.vport_group_manager (usually it is the PF/vport[0]), and its main responsibility is to forward each packet to the right vport. e-Switch needs to manage its own l2-table and FDB tables. L2 table is a flow table that is managed by FW, it is needed for Multi-host (Multi PF) configuration for inter HCA switching between PFs. FDB table is a flow table that is totally managed by e-Switch driver, its main responsibility is to switch packets between e-Swtich internal vports and uplink vport that belong to the same. This patch introduces only e-Swtich l2 table management, FDB managemnt will come later when ethernet SRIOV/VFs will be enabled. preperation for ethernet sriov and l2 table management.
