Steps to execute a program in Tofino:

1. Navigate to the SDE PATH :

     cd ~/bf-sde-8.x.x

2. Set the env variables :

     . ./set_sde.bash

3. Build the p4 program using the command :

     ./p4_build ddc/ddc.p4

4. Load the p4 program, and run the control plane API code using :

     "cd ddc/CP"
     "./run.sh"

Command to execute upon tofino reboot

     cd ~/bf-sde-8.x.x
     . ./set_sde.bash
     sudo ./install/bin/bf_kdrv_mod_load $SDE_INSTALL

Steps to execute a program in Netronome Nic:

1. Load the nfp kernel module :

     sudo modprobe nfp nfp_pf_netdev=0 nfp_dev_cpp=1

2. Start the run-time environment :

     sudo systemctl start nfp-sdk6-rte
     sudo systemctl start nfp-sdk6-rte-debug

3. Build the program using the below command :

     sudo nfp4build -s AMDA0096-0001:0 -l lithium -o <prog_name>.nffw -p nfp-build -4 <prog_name>.p4 

4. Load the firmware using the command :

     sudo nfp-nffw load -s <prog_name>.nffw

5. Load the design on the nic :

     sudo rtecli design-load -f <prog_name>.nffw -p nfp-build/pif_design.json -c user_config.json

Now you must see the vf interfaces in ifconfig.
