 * Allow user to specify output DLT.  The values for this should

 * DLT_EN10MB is ethernet, so I called the prefix "enet":
 * (--enet-src, --enet-dst, --enet-proto)
 * so the string I should look for here is "enet" too.  It's important
 * that the prefix you use here is also used as the "name" in the
