[ Upstream commit cbd7ec083413c6a2e0c326d49e24ec7d12c7a9e0 ]
When sending packets under 60 bytes, up to three bytes of the buffer
following the data may be leaked. Avoid this by extending all packets to
ETH_ZLEN, ensuring nothing is leaked in the padding. This bug can be
reproduced by running
$ ping -s 11 destination
