Dear Thierry :
For this driver, we can set it as 'n', and There is no rule of thumb as to which should default to y.
Thanks for your advice.
Thanks again.

Why is this selected by default? I can see that some of the other USB
network drivers are also selected by default, but not all of them. Is
there some rule of thumb as to which should default to y and which
shouldn't?
