This commit merges the driver_ops structures and implementations from
hostapd/driver*.[ch] into src/drivers. This is only an initial step and
there is room for number of cleanups to share code between the hostapd
and wpa_supplicant parts of the wrappers to avoid unnecessary source
code duplication.
The madwifi driver has interface to set probe request ie.
Attached patch will enable the functionality.
I could see probe request includes WSC IE with this patch.
