The short answer is yes.
The long answer is: Who cares? The important thing is that a corrupted frame
is not passed to an application and the probability of an undetected error is
not affected. Furthermore, although the count may not be "100% accurate", it
is pretty close to that. Keep in mind, for this error to be missed by the CRC
counter, it has to occur in the first six bytes of a frame AND not violate
the coding rules in the physical layer. I will leave it to you figure out the
probability for such an event, but I would assert that it is pretty low...
