+ * INET         An implementation of the TCP/IP protocol suite for the LINUX
+ *              operating system.  NET  is implemented using the  BSD Socket
+ *              interface as the means of communication with the user level.
+ *
+ *              Definitions for the Ethernet handlers.
+ *
+ * Version:     @(#)eth.h       1.0.4   05/13/93
+ *
+ * Authors:     Ross Biro, <bir7@leland.Stanford.Edu>
