I'm not sure if this is necessarily the right way, but 
changing the declaration for rtnetlink_rcv_skb() in 
net/core/rtnetlink.c from "extern" to "static" seems to have 
fixed the problem for me.  In any case, I couldn't find any 
external references to that function, so it seems to me that 
this is the way to go.
