Yea.

Also:  WRT a netlink message for REDIRECT events.  After thinking more
about this, it seems like users will already get notification of a
REDIRECT in the form of 2 messages, a RTM_DELROUTE for the old route and
a RTM_NEWROUTE message with the RTPROT_REDIRECT protocol type.  I think
this is perhaps sufficient for user mode notifications.  What do you
think?

For the RDMA kernel subsystem, however, we still need a specific event.
We need both the old and new dst_entry struct ptrs to figure out which
active connections were using the old dst_entry and should be updated to
use the new dst_entry.
