Writing Vlan driver

[Tekale Sharad-FHJN78]

    
Hi all, 
 
    My task is to write a Vlan driver. But I'm new to Linux device
drivers.
 
    Although I have written skull driver, but not yet confident on
writing device drivers.
   
    Can any point me to some tutorial that helps to quick start on
device drivers,
 
    also gives some information about writing a vlan driver.
 
Thanks In advance,
Sharad
