Invoking e100_open from userspace

[Prabhu nath <gprabhunath@xxxxxxxxx>]

Dear All,

            I am trying to analyse ethernet and rionet driver. Both the drives are registered with the kernel through
   register_netdev(). 
   Each driver has their own functions registered such as e100_open(), rionet_open(). How to trigger this functions from the user space. 

   Appreciate your help.

Regards,
Prabhu
