    IfAPI: More accessors
    
    Summary:
    Add the following accessors needed by infiniband drivers:
    * if_getaddrlen()
    * if_setbroadcastaddr()
    * if_resolvemulti()
    
    With these accessors, and additional changes on the drivers' side, an
    amd64 kernel can be compiled with `struct ifnet` completely hidden.
