+ * idiscover.c
+ * Discover all IPMI-LAN-enabled nodes on this network or subnet.
+ * This program is not completely reliable yet, not all IPMI-LAN-enabled
+ * nodes respond.
+ * Currently this utility is compiled with NO_THREADS, but threads can
+ * be enabled by commenting out this flag.

+ *
+ * 10/27/06 Andy Cress - created
+ * 05/01/07 Andy Cress - added -g for GetChannelAuthCap method,
+ * added -a logic for broadcast ping,
+ * updated WIN32 logic
+ * 09/20/07 Andy Cress - fixed send/receive thread order
+ * 07/15/08 Andy Cress - added -r for ping repeats
+ * 11/21/08 Andy Cress - detect eth intf and broadcast ip addr
+ * 01/04/16 Andy Cress - v1.11, allow 0 if fBroadcastOk (-a)
