      This ticket is tracking the QE verification effort for the solution to the problem described below.
      There are a couple of callers of rtnl_delete_link() in openvswitch which all call the function while holding the RTNL. However, the core caller (rtnl_dellink) has moved to rtnl_net_lock(), so when the kernel is compiled with the small RTNL enabled, the locking is no longer congruent.
