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. -- Fabien Chouteau
