hssi: update markdown docs for new test modes
## DESCRIPTION ##
The ```hssi``` application provides a means of interacting with the 10G and
-with the 100G HSSI AFUs. In both 10G and 100G operating modes, the application
-initializes the AFU, completes the desired transfer as described by the mode-
-specific options, and displays the ethernet statistics by invoking
-```ethtool --statistics INTERFACE```.
+with the 100G HE-HSSI AFUs. In both 10G and 100G operating modes, the application
+initializes the AFU and completes the desired transfer as described by the mode-
+specific options.
