>From my experimentation with netlink, RTM_NEWROUTE and RTM_DELROUTE messages do not get sent up for redirect events. I have, in fact, added this with the new patch I'll send out soon. So either way I need to change the IPv[46] code to generate a notification for redirects. With the single NETEVENT_REDIRECT call, the RDMA driver can, in one sweep, update all the connections. It seems more efficient. At the place where I've hooked redirect, both the old route and the new route are already created.
