| gif(4) talks about it.  IFF_LINK2 on gif(4) turns off ingress filtering.

It seems strangely bogus that gif(4) does this kind of filtering
and no other interface does. Why is gif special?

It seems to violate the principle of least surprise that this filtering
happens, so I wonder about the default.

Wouldn't it be best if the filtering took place at another layer?
