   4 Subject: [PATCH] rtl8xxxu: Do not mess with REG_FPGA0_XA_RF_INT_OE either on
   5  8188eu
   6
   7 On older devices the vendor driver hard codes a value into
   8 REG_FPGA0_XA_RF_INT_OE for antenna selection. This probably shouldn't
   9 be done in the first place, but more investigation needs to be done to
  10 figure out how this really works.
