OK. Is there any reason why IPv4 should be different from IPv6 in this respect though? If the split device dst's are to be kept, we'll need a way to clean them up. There are two choices: 1) Put the dst's on IPv6's own GC so that we can search by rt6i_idev. 2) Change the generic GC so that dst->ops->ifdown is always called even if dst->dev does not match with the device going down. We also need to change the individual ifdown functions to check for ->dev. The IPv6 ifdown function can then check for ->rt6i_idev as well. What's your preference?
