    if_tun: Some small tweaks and cleanups
    
    * Consistently use the TUN define instead of "tun".
    
    * Use variable "sc" instead of "tp" to refer to "struct tun_softc".
    
    * Use variable "ifp" (struct ifnet *) to make code more readable.
    
    * Static the bitmap variable.
    
    * Various style tweaks.
