That's not how IEEE 802.11 defines IBSS.. No new IBSS should be created
if there are existing stations using the same SSID.

It would be up to the driver to notify that the connection is completed.
I have done only limited testing of adhoc networks with Linux drivers,

This has actually already been implemented and is somewhere on my
things-to-merge list.. However, that frequency is _not_ for locking the
channel to avoid joining an existing network, it is for giving the new
channel for the case where no existing network is available.
