Pyun YongHyeon 161bc8e475 Remove link state change callback handler. There is no need to ... register both status change and link state change callbacks. Implement checking valid link in state change callback and poll active link state in vr_tick(). This allows immediate detection of lost link as well as protecting driver from frequent link flips during link renegotiation. taskq implementation was removed because driver now needs to poll link state in vr_tick(). While I'm here do not report current link state if interface is not running. Tested by: n_hibma MFC after: 1 week		2011-06-22 02:18:45 +00:00
