Hi Marcos,

As discussed, there is 2 scenarios:

1- Ship in the night installation of SONIC & RARE/freeRtr
    Run either SONIC or RARE/freeRtr one at a time using the whole box.

2- Ship in the night installation and run both in parallel using different 
pipe of the TOFINO
    Run SONIC and RARE/freeRtr AT_THE_SAME_TIME

-1- you don’t need container, the installation we have done together is 
sufficient.
     If you want to use container, it would be better to use either stratum 
SDE granted the fact that stratum/SONIC SDE is providing bf_kpkt
     Or build s dedicated SDE for RARE/freeRtr with bf_kpkt.

-2- it would need to either have 1 different CPU port for each SONIC and 
RARE/freeRtr.
      If not possible an shim GRPC layer that would relay the packets to 
RARE/freeRtr or SONIC depending on the pipe_id.

However, I have some doubts here as SONIC is using SAI and not GRPC (Or maybe 
SAI is using GRPC).

IIRC, run_switchd.sh is a helper shell script for running bf_switchd, I 
presume it is possible to run bf_switchd links in stratum

You’ve discovered yourself that bf_kdrv cannot be run at the same time than 
bf_kpkt. However, what you can test is enable bf_kpkt.
- Compile and launch one P4 program that uses port 192 (bf_pci0) 
- and compile and launch a P4 program that uses port 64 (that should be the 
MAIN BOARD CPU internal Ethernet port)

And check from that you are receiving packets from both port.

Or simpler, raise this question against INTEL BXD ICRP forum.
