   4 Subject: [PATCH] rtl8xxxu: Implement rtl8188eu_init_phy_rf()
   5
   6 Include the table rtl8188eu_radioa_init_table derived from vendor
   7 driver. The vendor table relies on a hack setting RF6052_REG_RCK1 +
   8 RF6052_REG_RCK2 with delays. This workaround is open coded here
   9 instead of modifying the table parsing code.
