But is this in the correct 'address space' for the want of a better term. Everything else to do with PSE is in the networking domain of netlink. ethtool is used to configure PSE. Shouldn't the notification also close by to ethtool? When an interface changes state, there is a notification sent. Maybe we want to piggyback on that? Also, how do regulator events work in combination with network namespaces? If you move the interface into a different network namespace, do the regulator events get delivered to the root namespace or the namespace the interface is in? Andrew
