How to read out the driver in use?

hi,
I want to read out which Wifi driver I am using. I know it is the Broadcom STA wireless driver but I need to know the exact name to add it to /etc/network/interfaces.

Thanks.

Why do you want to do this?
As far as I know you should not need to put the network module (driver) name in /etc/network/interfaces

This is my /etc/network/interfaces

Code:

---

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0

---

There is no mention of my wifi interface
