Hi all,

I am trying to clarify a few things about how the hardware, transport and software error counters are working. In particular for my mind makes sense to have a hierarchy like hardware -> transport -> software. In this model an error counter increased in hardware will be expected to be propagated up, and we will expect to see transport and software error as well. However I would never expect the revers to happen. Assuming there is no hardware failures, a software err should not increase the transport or hardware err counter, or transport should never increase hardware err count. Is this how the counters are working or I am missing something?
