Subject: [PATCH RFC net-next 0/2] Take care of xfrm policy when checking dst entries

The goal of these patches is to fix the following problem: a session is
established (TCP, SCTP) and after a new policy is inserted. The current
code does not recalculate the route, thus the traffic is not encrypted.

The patch propose to check flow_cache_genid value when checking a dst
entry, which is incremented each time a policy is inserted or deleted.

Patches are tested with TCP and SCTP.

Comments are welcome.

Regards,
Nicolas
