 A non-INET6 kernel may not use the "stf" pseudo-device. Remove that as well
 and it should compile.

 This is non-trivial and should be documented next to the INET6 option.

 Err.. it used to work.  Is it my breakage?  Does not appear so.

 I am not sure. Doesn't this need INET6 to work? It complains at link time
 not finding:

     if_stf.c:(.text+0x4e8): undefined reference to `ip6_pktq'

 Anyway, I added #error to it.
