====================
This series handles IPoIB child interface creation with setting
interface's HW address.

In current implementation, lladdr requested by user is ignored and
overwritten. Child interface gets the same GID as the parent interface and
a QP number which is assigned by the underlying drivers.

In this series we fix this behavior so that user's requested address is
assigned to the newly created interface.

As specific QP number request is not supported for all vendors, QP number
requested by user will still be overwritten when this is not supported.

Behavior of creation of child interfaces through the sysfs mechanism or
without specifying a requested address, stays the same.

If in the process of creating the underlay QP for an IPoIB interface
the user has set the address and specifically the 1st-3rd bytes
representing the QP number, use the requested QP number when creating
the underlay QP.

For a user to be able to request a QP number on QP creation, the MKEY_BY_NAME
NVCONFIG should be set. As mkey_by_name and qp_by_name are coupled in FW.
This requires driver to query the mkey_by_name max cap during initialization

ib_unregister_device_queued() can only be used by drivers using the new
dealloc_device callback flow, and it has a safety WARN_ON to ensure
drivers are using it properly.

However, if unregister and register are raced there is a special
destruction path that maintains the uniform error handling semantic of
'caller does ib_dealloc_device() on failure'. This requires disabling the
dealloc_device callback which triggers the WARN_ON.

Instead of using NULL to disable the callback use a special function
pointer so the WARN_ON does not trigger.

ipoib_mcast_carrier_on_task() insanely open codes a rtnl_lock() such that
the only time flush_workqueue() can be called is if it also clears
IPOIB_FLAG_OPER_UP.

Thus the flush inside ipoib_flush_ah() will deadlock if it gets unlucky
enough, and lockdep doesn't help us to find it early:

          CPU0               CPU1          CPU2
   __ipoib_ib_dev_flush()
      down_read(vlan_rwsem)

                         ipoib_vlan_add()
                           rtnl_trylock()
                           down_write(vlan_rwsem)

				      ipoib_mcast_carrier_on_task()
					 while (!rtnl_trylock())
					      msleep(20);

      ipoib_flush_ah()
	flush_workqueue(priv->wq)

Clean up the ah_reaper related functions and lifecycle to make sense:

 - Start/Stop of the reaper should only be done in open/stop NDOs, not in
   any other places

 - cancel and flush of the reaper should only happen in the stop NDO.
   cancel is only functional when combined with IPOIB_STOP_REAPER.

 - Non-stop places were flushing the AH's just need to flush out dead AH's
   synchronously and ignore the background task completely. It is fully
   locked and harmless to leave running.

Which ultimately fixes the ABBA deadlock by removing the unnecessary
flush_workqueue() from the problematic place under the vlan_rwsem.
