Why is special treatment needed for small packets? Is this simply masking a bug elsewhere -- the original qemu driver must have dealt with small packets (e.g., TCP acks) correctly.

extend the ether packet to 60 bytes else the guest ethernet driver will report error.
in fact, the patch is borrowed from qemu ne2000.
