Thanks Jouni Malinen. I have visited the link you have referred.
When i run hostapd with the specific .conf file, i have specfied
driver=madwifi in the conf file. But it is throwing error as "Line 2:
invalid/unknown driver 'madwifi' ".
Will mac80211_hwsim run without any driver dependency ?
Thanks for your time.
