Skbs are those tiny bits which allow 100 Gbit/s forwarding between multiple
interfaces. But of course it can not be as fast as plain memory copy :)

Having one skb allocation per IO syscall will be challenging but after
all we have this for send/recv calls and achieve high performance
numbers. Idea with merging events in the same skb will be also very non-trivial.
