/*
 *  This defines Version 2 of Spider's STREAMS Data Link protocol.
 *  Its main feature is its ability to cope with hardware addresses
 *  of length not equal to 6.
 */

/*
 *  Data Link ioctl commands.
 *
 *  To determine the version of the protocol in use, use the DATAL_VERSION
 *  command, and assume Version 0 if this fails with EINVAL.  (Yuk.)
 *
 *  The ETH_* commands will work for any current version of the protocol,
 *  but only for Ethernet drivers (hw_type == HW_ETHER).
 *
 *  Hardware types are defined in dl_proto.h.
