Leonid Arsh 7a343d4c46 IPoIB: P_Key change event handling ... This patch causes the network interface to respond to P_Key change events correctly. As a result, you'll see a child interface in the "RUNNING" state (netif_carrier_on()) only when the corresponding P_Key is configured by the SM. When SM removes a P_Key, the "RUNNING" state will be disabled for the corresponding network interface. To implement this, I added IB_EVENT_PKEY_CHANGE event handling. To prevent flushing the device before the device is open by the "delay open" mechanism, I added an additional device flag called IPOIB_FLAG_INITIALIZED. This also prevents the child network interface from trying to join to multicast groups until the PKEY is configured. We used to get error messages like: ib0.f2f2: couldn't attach QP to multicast group ff12:401b:f2f2:0:0:0:ffff:ffff in this case. To fix this, I just check IPOIB_FLAG_OPER_UP flag in ipoib_set_mcast_list().
