Possible bug in the code

[subodh-malgonde]

I was just going through the Python code for the host. Found this line:

min/host/min.py

Lines 557 to 558 in 9e87a79

	if (self._sn_max - self._sn_max) & 0xff > window_size:
	raise AssertionError

self._sn_max - self._sn_max will always be zero and the if condition will always evaluate to False.
