Re: [RFC] mac80211: minor cleanup

Hi Johannes and all,

i have a doubt why we should stop scanning in the following scenario:

*we have created an IBSS network as we cannot find no other network for 
IBSS_JOIN_TIMEOUT and when we had used 'fixed-freq' option, why can't we 
still keep scanning in the fixed frequency?

*we create two networks IBSS1 and IBSS2 with 'fixed-freq' option and 
they are not visible to each other till they had become 
creators(IBSS_JOIN_TIMEOUT). i assume unless we scan in the 'fixed-freq'
they won't be joining with each other as they have their own 'BSSID' 
which won't match when we receive each of their beacon frames. i will 
test this scenario to
confirm.  thanks in advance

thanks to Raj for his valuable inputs.
