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.
