[PATCH net-next 0/2] refactor the ringtest testing for ptr_ring

tools/include/* have a lot of abstract layer for building
kernel code from userspace, so reuse or add the abstract
layer in tools/include/ to build the ptr_ring for ringtest
testing.

The same abstract layer can be used to build the ptr_ring
for ptr_ring benchmark app too, see [1].
