This change makes it so that we use a software path for packets that are going to be locally switched between two macvlan interfaces on the same device. In addition we resort to software replication of broadcast and multicast packets instead of offloading that to hardware. The general idea is that using the device for east/west traffic local to the system is extremely inefficient. We can only support up to whatever the PCIe limit is for any given device so this caps us at somewhere around 20G for devices supported by ixgbe. This is compounded even further when you take broadcast and multicast into account as a single 10G port can come to a crawl as a packet is replicated up to 60+ times in some cases. In order to get away from that I am implementing changes so that we handle broadcast/multicast replication and east/west local traffic all in software.
