Subject: [DISCUSSION] rt6i_genid

Hello Nicolas

Commit 6f3118b571b8a4c06c7985dc3172c3526cb86253: "ipv6: use net->rt_genid to check dst validity"
makes ip6_dst_check to check rt6i_genid against with struct net->rt_genid,
As a matter of fact, struct net->rt_genid could only be modified by two places,
first is adding/delete IPv4 address, second is inserting new XFRM policy.

Is there any other considerations that adding/deleting IPv4 address would invalid all IPv6 dst
as well? because I'm working a patch which actually depends on the result of this question.

Thanks
