This patch is necessary because some NICs are configured to drop short frames,
therefore the OS will not receive some of the packets generated by Qemu.

There's a first patch to fix this issue:
http://git.savannah.gnu.org/cgit/qemu.git/commit/?id=dbf3c4b4baceb91eb64d09f787cbe92d65188813

My patch fixes two other sources of short frames.
