Hi Ilia, Thanks for the doc patch.
+Profiling wasted iterations with ITT +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Probably better to call this VTune ITT
+ +Iterations that yielded no RX packets (wasted loop iterations) can be +analyzed using Intel® VTune\ :sup:`TM` Amplifier.
You don't need a superscript here. You can use the TM symbol directly like the previous (R) symbol.
