Re: [Madwifi-devel] channel bandwidth 5/10 MHz operation

[Dino J. M. <din...@ya...>]

Hasan,
  i had added a test version with freq enabling from 5520 to 5900 in half and quarter bandwidth, pasted teh code below. After doing the below changes if i put wlanconfig ath0 list freq , its showing all the half and quarter bandwidth freq. 

Now need to configure the madwifi to use a particular bandwidth.
