+
+# Purpose: Stream BG data from FN1 to FN0, forward this data from FN0 to dop17 
+# Description: 
+# . BG outputs blocks of 365 32b words = 1460 bytes;
+# . BG uses inter-block gap size of 9*365 words to limit BG output rate to 
+#   1/10th of max
+# . BG theoretical max output rate is 200MHz*32b = 6.4Gbps
+# . The above translates to an ethernet data rate of about (6.4Gbps/10) 640Mbps
+#   (excluding packet overhead).
+# Usage: python tc_compaan_unb1_dp_offload_bg_lb.py --unb # --fn 0,1
+#        . Use tcpdump to view the received packets.
