dst stored in struct sctp_transport needs to be recalculated when ipsec policy

For example, if a SCTP connection is established and then an IPsec policy is
set, the old SCTP flow will not be updated and thus will not use the new
IPsec policy.

why doesn't this need to be done for TCP? What makes SCTP special in this case?
ip_queue_xmit does an __sk_dst_check() which is essentially what
sctp_transport_dst_check() does. That should determine if the currently cached
route is valid or not.
Looks like sctp may need to change to using ip_route_output_ports() call
as ip_route_output_key may not do all that is necessary
I try, but it doesn't solve the problem. In fact, it seems better to use
ip_route_output_ports(), would you like me to send a patch?

Nicolas
