In the realm of straw ideas, how often are netdevs added and removed,

In certain cases...say, with vlans, you could very often create and
destroy net devices. I think that giving up and leaking the memory
is not a good idea.
I think he's suggesting another thing. Reattach the skb->dev
to some dummy device that always persists, when a device goes
down.
Actually, I think that Ben had me pegged right the first time - I was not going
to chase down all the skb's (assuming there isn't already a list of all skb's) I
was just going to leave the minimum of a devices structures out there so it
would still be "safe" to follow the pointer from the skb's etc.
The only problem is finding all SKB's that reference the
dev going down.
Indeed.
