   4 Subject: [PATCH 05/21] wifi: rtl8xxxu: support setting mac address register
   5  for both interfaces
   6
   7 To prepare for concurrent mode, enhance rtl8xxxu_set_mac() to write the
   8 mac address of the respective interface to REG_MACID or REG_MACID1.
   9
  10 Remove the call to rtl8xxxu_set_mac() from the init function as we set
  11 it in rtl8xxxu_add_interface() later anyway.
  12
  13 Until rtl8xxxu_add_interface() can handle both interfaces, call
  14 rtl8xxxu_set_mac() with port_num = 0.
