Command 'ip link ... set nomaster' causes that ice_plug_aux_dev()\n   is called from ice_service_task() context, aux device is created\n   and associated device->lock is taken.\n2. Command 'ip link ... set master...' calls ice's notifier under\n   RTNL lock and that notifier calls ice_unplug_aux_dev(). That\n   function tries to take aux device->lock but this is already taken\n   by ice_plug_aux_dev() in step 1\n3. Later ice_plug_aux_dev() tries to take RTNL lock but this is already\n   taken in step 2\n4. Dead-lock\n\nThe patch fixes this issue by following changes:\n- Bit ICE_FLAG_PLUG_AUX_DEV is kept to be set during ice_plug_aux_dev()\n  call in ice_service_task()\n- The bit is checked in ice_clear_rdma_cap() and only if it is not set\n  then ice_unplug_aux_dev() is called. If it is set (in other words\n  plugging of aux device was requested and ice_plug_aux_dev() is\n  potentially running) then the function only clears the\n---truncated---",
