Subject: [PATCH v3 02/17] staging: rtl8723bs: remove code related to unsupported channel bandwidth
remove all code related to unsupported channel
bandwidth (i.e. 80, 80+80, 160 Mhz). rtl8723bs NIC
works only on 20 and 40 Mhz channels.
Module parameter rtw_bw_mode can only have two
values: 0 and 1 (20 Mhz and 40Mhz). So modify
the default value setting to zero the 5Ghz nibble.
Comments modified accordingly.
