    net/mlx5: E-Switch, Add SR-IOV (FDB) support · 81848731

    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.
