Subject: [Patch net 0/2] netem: Fix skb duplication logic to prevent infinite loops

This patchset fixes the infinite loops due to skb duplication in netem.

This replaces the patches from William, with much less code and without
any workaround. More importantly, this does not break any use case at
all.
