      bnx2: Allow phy reset to be skipped during chip reset. · 9a120bc5
      Michael Chan authored
      Andy Gospodarek <andy@greyhouse.net> found that netconsole would
      panic when resetting bnx2 devices.
      
      >From Andy:
      "The issue is the bnx2_set_link in bnx2_init_nic will print a link-status
      message before we are fully initialized and ready to start polling.
      Polling is currently disabled in this state, but since the
      __LINK_STATE_RX_SCHED is overloaded to not only try and disable polling
      but also to make the system aware there is something waiting to be
      polled, we really have to fix this in drivers.
      
      The problematic call is the one to netif_rx_complete as it tries to
      remove an entry from the poll_list when there isn't one."
      
      While this netconsole problem should be fixed separately, we really
      should not reset the PHY when changing ring sizes, MTU, or other
      similar settings.  The PHY reset causes several seconds of unnecessary
      link disruptions.
