Registering ATM devices.

Registering ATM devices.

[Sanjay Kumar]

Dear all,

I have MPC8266 having connected two UTOPIA II interface on FCC1 and FCC2.
UTOPIA II interface connected to FCC1 has 16 PHY devices connected to it
and UTOPIA II interface connected to FCC2 has 2 PHY devices connected to
it.
                    while registering the atm devices via
atm_device_register() function should I register two atm devices, one for
each UTOPIA II interface conncetd to FCC1 and FCC2 or 18 atm devices for
each PHY devices connected on both UTOPIA II interface.Total number of PHY
devices on both UTOPIA II interface is 18.

Any suggestion will be helpfull to me.

with regards,
sanjay

Hi Sanjay,

I think it would be best to register one driver for each PHY otherwise you whount have any information what interface a new
connection is assigned to.
On the oher hand I am not shure if there is enough protection against parallel access of different device drivers running at the
same hardware...

Regards, Stephan
