RE: missing info in the document for qemu networking (where to find linux-test-xxx.tar.gz) (TAP networking)

Instead of using -device virtio-net-pci, I tried using -device e1000,
But this time it gives me 'EEPROM Checksum Is Not valid' error.

And it resets the MAC address and the network service can't run. (I found there 
was NetworkManager-wait-online failure during the boot in the previous method).
 How should I know the e1000 NIC's default MAC address?(so that I want to avoid 
the EEPROM checksum error?)
Or can I change MAC address inside the guest machine later?
Thanks
