    net/mlx5: Introducing E-Switch and l2 table · 073bb189
    Saeed Mahameed authored
    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
    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.
