Hi,
aside from the aspects of getting this properly signed off and merged,
this opens up a question. What does resetting a hub do to its children?
That is if the request to wake up comes from a child, do we
a) lose state in the child?
b) retain the knowledge which port requested the wakeup?
How far has this patch been tested?
Regards
Oliver
