Oh, for legacy we still depend on chan_type setting for sometime?

ok. I will change the channel config structure per 11ac spec.

dot11CurrentChannelBandwidth
       Channel bandwidth. Possible values represent 20 MHz, 40 MHz,
       80 MHz, 160 MHz and 80+80 MHz channels.

dot11CurrentChannelCenterFrequencyIndex0
       In 20 MHz, 40 MHz, 80 MHz and 160 MHz channels, denotes
       the channel center frequency.In 80+80 MHz channels, denotes the
       center frequency of the frequency segment 0, which is the
       frequency segment containing the primary channel.
       Valid range is 1 to 200.

dot11CurrentChannelCenterFrequencyIndex1
       In 80+80 MHz channels, denotes the center frequency of the fre-
       quency segment 1, which is the frequency segment that does not
       contain the primary channel.Valid range is 1 to 200.
       Undefined for 20 MHz, 40 MHz, 80 MHz and 160 MHz chan-
                                    nels.
dot11CurrentPrimaryChannel
       Denotes the location of the primary 20 MHz channel.
       Valid range is 1 to 200.
