vcc_release_async() don't work with pppoatm, I don't know why,
simply after disconnect modem, ppp demon still works 
and ifconfig command show me connection is ok.
Using vcc->push(vcc, NULL) kill pppd with
Modem hangup message in logs.

It depends on approach, someone would like to finish connection when 
net driver module is unloaded, other one would like to prevent unloading 
module. I preffer second approach as is in (for example) pppoatm .

Adding try_module_get and module_put pair in subdriver atm_start() and atm_stop() 
propably block unload module anyway.
