      ixgbe: Use netdev_<level>, dev_<level>, pr_<level> · 849c4542
      Emil Tantilov authored
      This patch is alternative to a previous patch submitted by Joe Perches.
      
      Create common macros e_<level> and e_dev_<level> that use netdev_<level> and
      dev_<level> similar to e1000e.
      Redefined pr_fmt for driver messages.
      Use %pM to display MAC address.
      Aligned text to better match the new format.
