   4 Subject: [PATCH 04/14] net: dpaa2: replace dpaa2_mac_is_type_fixed() with
   5  dpaa2_mac_is_type_phy()
   6
   7 dpaa2_mac_is_type_fixed() is a header with no implementation and no
   8 callers, which is referenced from the documentation though. It can be
   9 deleted.
  10
  11 On the other hand, it would be useful to reuse the code between
  12 dpaa2_eth_is_type_phy() and dpaa2_switch_port_is_type_phy(). That common
  13 code should be called dpaa2_mac_is_type_phy(), so let's create that.
  14
  15 The removal and the addition are merged into the same patch because,
  16 in fact, is_type_phy() is the logical opposite of is_type_fixed().
