either in P4 DPDK or bmv2

need entry into conntrack table
routing->mapping->flows

table to make decision may be CA/PA or other into conntrack table

P4 does not support

Can do early lookup w/o add-on-miss? Then access conntrack table again if there is a miss the 1st time.

Way to solve might be to create the SW agent under development by @r12f

When we present FLOW API, we can look at add-on-miss gaps

hi @r12f - do you think this is resolved by the Flow API that we published? TY!

hi @r12f - do you think this will be resolved by the DataPlane app/APIs that we are developing?
