After commit 05b35e7eb9a1 ("smsc95xx: add phylib support"), link changes are no longer propagated to usbnet. As a result, rx URB allocation won't happen until there is a packet sent out first (this might never happen, e.g. running just ssh server with a static IP). Fix by triggering usbnet EVENT_LINK_CHANGE.
