   4 Subject: [PATCH 03/21] wifi: rtl8xxxu: support setting linktype for both
   5  interfaces
   6
   7 To prepare for concurrent mode, enhance the set_linktype function to be
   8 able to set the linktype in the MSR register for both hardware ports.
   9
  10 Until the users of set_linktype can handle multiple interfaces, use
  11 port_num = 0.
