wpa_cli select nework x -> causes what?

[ArneKeller at gmx.de]

Hello list,

can someone tell me which functions are called when doing a "wpa_cli 
select nework x".

This causes a card down time of 300ms where no packets where forwarded 
to the kernel.
I need this functionality to simualte a handover from one to another 
access-point in my diploma thesis.

The 300ms interruption is independen from the authentication mechanisme.


regards
arne
