Yes, this was my initial assumption that the package when and if it is 
released for RHEL would get pushed back into the NFV SIG in the cbs 
mirrors. However, the RHEL RM people internally in RH asked where/how 
they push the VPP packages to back to Centos to which led me to be 
curious as to how exactly they propagate packages back to Centos.
