[P4-dev] Match + Actions on a cloned packet

Hi All,

I have few doubts on cloned packets:

1. When the packet is cloned using clone_ingress_to_egress primitive,
is the match+actions which are mentioned in ingress pipeline only
applicable to original packet or to the cloned packet as well?
In the diagram given in the spec (section 14.1.2), the cloned
packet is directly going to the buffering mechanism.

2. When we inject the packet through the application which
is listing an a particular port, what is the control flow of that
packet. Is it go again ingress pipeline match+actions tables.

Thanks & Regards,
Ramana
