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.
