I guess your meaning is:
for net2272.c and net2280.c, we still need driver->disconnect. although for others do not need.
if it is correct:
I will try to find another members which have relative HW to help us to test it.
e.g. communicate with the relative company to help test their own product.
e.g. find another relative members with net22??.c which have HW and can help us.
if I can not find other members to help us, I will try to find another ways.
if so, maybe I need more time to do it.
if so, I am sorry to have to delay the time point (2013-3-15)
and I guess the new time point is within a month (before 2013-4-15)
all together: I beleive "ways is always more than issues".
BTW:
I also add comments for your test program, please check whether it is ok, thanks.
