Permission to submodule 'switchsai/submodules/ocpsai'

[Lineson]

Hello,

I'm trying to reproduce the int-demo result. However, in the step 'Build and run PTF tests' with command

cd ntf/bmv2
./run_build_for_ptf.sh

how can I get permission to the submoduleswitchsai/submodules/ocpsa ?

Here is the log:

Submodule path 'switchsai/submodules/SAI': checked out '8c2a003e02d04e8839f7779ec019dd505b6f34bb'
Cloning into 'switchsai/submodules/ocpsai'...
