select() with Network device driver

Hello,
I am trying to do a select() on a net interface. I need
the poll functionality of a char driver. That is - I want the select
to block until a certain condition in the driver/hardware becomes
true. This condition is notified to me by the interrupt handler.

Can somebody point out to how the select() works for sockets. It goes
to the tcp_select() or udp_select() in the network subsystem. However

I want it to go to the net interface.

Pointers to related info would be helpful.

Thanks
Himanshu
