This patch adds a simple memset() call that makes the warning dissapear.
an older, slower packet capture mechanism on Linux. Before Linux
2.6.27, the packet ring mechanism uses different-sized kernel
structures on 32- and 64-bit architectures, so a 32-bit program will
not run correctly on a 64-bit kernel. The older mechanism does not
have this flaw.
