Currently, unicast/multicast loopback raw ethernet (non-RDMA) packets are sent back to the vport. A unicast loopback packet is the packet with destination MAC address the same as the source MAC address. For multicast, the destination MAC address is in the vport's multicast filter list. Moreover, the local loopback is not needed if there is one or none user space context. After this patch, the raw ethernet unicast and multicast local loopback are disabled by default. When there is more than one user space context, the local loopback is enabled. Note that when local loopback is disabled, raw ethernet packets are not looped back to the vport and are forwarded to the next routing level (eswitch, or multihost switch, or out to the wire depending on the configuration).
