assign_name() creates a name MODEL.NUM, where MODEL is the client's model, and NUM is the number of MODELs that already exist. Markus added NIC naming for non-VLAN clients in commit 53e51d85. commit d33d93b2 incorrectly added a judgement of net-hub. It caused net clients created with -netdev get same names. eg: # qemu-upstream -device virtio-net-pci,netdev=h1 -netdev tap,id=h1 \ -device virtio-net-pci,netdev=h2 -netdev tap,id=h2 ..
