Hi;

We're working on wiring up our Qemu BMC via a TAP configuration, and we're
not seeing packets inside the Nuvoton NIC itself (a level of debugging we
had to enable).  We're using the npcm7xx SoC device,

-nic
tap,fds=4:5:6:7:8:9:10:11,id=net0,model=npcm7xx-emc,mac=58:cb:52:18:b8:f7

For the networking parameters, where the tap fds are valid.  I was curious
if any of y'all got qemu networking working for your BMC SoCs, either
Aspeed or Nuvoton?
