IEEE 802.3 standard requires Ethernet frames to be at least 64 bytes long.
If it is not the case, they will be considered as runt frames, and may be

IMO slirp is not the best place for this, e.g. virtio-net
does not need the padding.

I don't think it matters if virtio-net needs it or net; slirp should comply to RFC and standards, so it should make frames the correct size.
